3 つの見た目と、ステータスの有無
タグは、それが何であるか、どんな状態にあるかを示す単語や短い語句です。記事のカテゴリー、ビルドの結果、リリースの段階、複数の値のうちの既定値などに使います。レイアウトの中に、隣のテキストと同じ行に並び、ポインター、キー、フォーカスのいずれにも反応しません。
Web では <tanrei-tag> です。ほかのプラットフォームはまだ実装していません。

tonal の上に描いています。| パーツ | 説明 |
|---|---|
1 container | The shape that holds the label: at least the height of its size, a pill in the default system, filled in the tonal and filled looks and edged in the outlined look. It carries no state: nothing about it answers a pointer, a press or focus. |
2 label | The word or short phrase the tag shows, on one line. |
3 icon · 任意 | A leading glyph of the system's icon set that the product names (a category's mark, a status's mark). Decorative: the label says what the tag means. |
4 dot · 任意 | A small filled circle in the leading position, in the look's mark color: the lightest way to show a status beside its word. Drawn where the product asks for it and no glyph is given, and always on an outlined tag that has a status. |
5 outline · 任意 | The outlined look's edge: one hairline inside the container, the same in every status. |

tonal の上に描いています。プロパティ
| プロパティ | 型 | 既定値 | 説明 |
|---|---|---|---|
label | string | "" | The tag's text: a word or a short phrase ("Beta", "Out of stock"). It is what the tag draws and what assistive technology reads. |
variant | tonal | outlined | filled | "tonal" | How much the tag weighs. tonal: a quiet fill, the default. outlined: no fill and one hairline, for many tags close together. filled: a full fill, for the chosen one among its neighbours (the default among values, the required among fields) and for the one status that must not be missed. |
status | default | info | warning | error | success | "default" | What the tag reports, in the names the snackbar uses. default: a category or a neutral state, in the look's own colors. info, warning, error and success draw the look in that status's color roles. It changes colors only; the words are the label's and statusLabel's. |
statusLabel | string | "" | The status in words, in the product's language ("Error"), read by assistive technology before the label and not drawn. For a tag whose label does not itself say the status (an error tag that reads "3 builds"); a label that says it ("Failed") needs none. Ignored while status is default. |
size | small | medium | "medium" | Small (20 high, 12 text) follows a field's label, a table cell or a line of body text without making the line taller; medium (24 high, 14 text) stands beside a heading or by itself. |
dot | boolean | false | Draws the dot before the label, in the look's mark color. A glyph in the icon slot takes its place. An outlined tag with a status draws the dot whatever this says, because nothing else in that look shows the status. |
disabled | boolean | false | Draws the tag as part of something disabled — the label of a disabled field, a disabled row of a list, a disabled item of a menu — in its look's disabled colors, so that it fades with what it stands in. It changes nothing else: a tag takes no input and no focus, and what assistive technology hears of the disabled state it hears from the element the tag stands in. The component that holds the tag sets it (a Field does, for its requirement tag); a product sets it on a tag it places in a disabled element of its own. |

振る舞い
EARS 記法による要件です。各プラットフォームの実装は、この ID に対応するテストで検証されます。要件の原文は仕様ファイルのものをそのまま掲載しています。
| ID | 要件 |
|---|---|
TAG-1 | THE tag SHALL draw a container at least the height of its size (comp.tag.container.height.medium for medium, and so on) with corners comp.tag.container.shape, never larger than half the container's height (a pill where the value is sys.shape.corner.full, at any height the tag grows to) and eased by sys.shape.corner-smoothing, and lay out in one row its glyph or its dot, where it has one, and its label, comp.tag.container.gap apart; the start SHALL be padded by comp.tag.container.padding-inline-with-icon.medium where it holds the glyph or the dot and by comp.tag.container.padding-inline.medium where the label meets it, the end by comp.tag.container.padding-inline.medium, and the row's tallest item (the label's line or the glyph's box) SHALL be padded at the top and bottom by at least comp.tag.container.padding-block.medium (and so on for each size). THE tag SHALL be as wide as its content and its paddings, never wider than its layout gives it, and SHALL draw no elevation. |
TAG-2 | WHILE status is default THE tag SHALL fill its container with the container color of its variant and draw its label, and its glyph or dot, in that variant's label and icon colors: comp.tag.tonal.container.color, comp.tag.tonal.label.color and comp.tag.tonal.icon.color for tonal, and outlined's and filled's tokens of the same names (comp.tag.outlined.container.color, comp.tag.filled.container.color, and so on). |
TAG-3 | WHILE status is info, warning, error or success THE tag SHALL draw its container, its label and its glyph or dot from the parts of its variant prefixed with the status: for a tonal info tag comp.tag.tonal.info.container.color, comp.tag.tonal.info.label.color and comp.tag.tonal.info.icon.color; for outlined and filled, and for warning, error and success, their own tokens of the same names (comp.tag.outlined.error.icon.color, comp.tag.filled.success.container.color, and so on). A status SHALL change these colors only: the tag's size, shape, layout and edge stay those of its variant and size, and the tag SHALL NOT draw a glyph the product did not give. |
TAG-4 | WHILE variant is outlined THE tag SHALL draw an edge comp.tag.outline.width wide in comp.tag.outline.color inside its container's size, following its corners, in every status, without changing the tag's size or the place of its content; WHILE variant is tonal or filled it SHALL draw no edge. A status SHALL NOT color the edge: it is the system's one hairline. |
TAG-5 | THE tag SHALL set its label on one line in the text style of its size (comp.tag.label.typescale.medium for medium, and so on) and the label color of its look (TAG-2, TAG-3), SHALL NOT wrap it, and SHALL cut it with an ellipsis only when the layout gives the tag less width than the label needs, keeping its paddings and its glyph or dot whole; the full label SHALL remain what assistive technology reads. |
TAG-6 | WHERE the icon slot holds a glyph THE tag SHALL draw it before the label in a box of comp.tag.icon.size, centred on the label's line, in the icon color of its look (TAG-2, TAG-3), with sys.icon.family.unselected and sys.icon.fill.unselected, sys.icon.weight and an optical size clamped between sys.icon.optical-size.min and sys.icon.optical-size.max, SHALL keep it from assistive technology, and SHALL draw no mark of its own in its place. |
TAG-7 | WHILE dot is true and the icon slot is empty THE tag SHALL draw before the label a filled circle of diameter comp.tag.dot.size in the icon color of its look (TAG-2, TAG-3), centred on the label's line, a circle whatever corners the container has, and SHALL keep it from assistive technology; WHERE the icon slot holds a glyph THE tag SHALL draw the glyph and no dot. |
TAG-8 | WHILE variant is outlined and status is info, warning, error or success and the icon slot is empty THE tag SHALL draw the dot of TAG-7 whether dot is true or false, because an outlined tag keeps the surface's label color and the one hairline in every status, so its mark is the only place the status shows. |
TAG-9 | THE tag SHALL NOT take pointer, touch or keyboard input, SHALL NOT take focus or be a stop in the focus order, and SHALL NOT change anything it draws under a pointer, a press or focus: it has no hovered, focused, pressed or selected state and no disabled state of its own — disabled draws it as part of something disabled and changes nothing it does (TAG-21) — draws no state layer, no ripple and no focus indicator, and emits no event. |
TAG-10 | WHERE the tag is placed inside an element that takes input (a link, a button, a list item, a table row, a card that is pressed as a whole) THE tag SHALL let input over it reach that element, SHALL stay as it is drawn while that element is hovered, focused or pressed (the state is drawn by that element, on its own container), and SHALL add its text (TAG-11) to that element's content in reading order; it SHALL NOT become a second target inside it. |
TAG-11 | THE tag SHALL expose its label as plain text, read where the tag sits, with no role, name or state of its own; WHILE status is not default and statusLabel is not empty THE tag SHALL expose statusLabel before the label as part of that text, set apart so that the two are read as two phrases ("Error, 3 builds"), and SHALL NOT draw it; WHILE status is default THE tag SHALL ignore statusLabel. THE tag SHALL NOT expose its variant, its size or its status in any other way: a status is given in words or not at all. |
TAG-12 | WHEN label, status or statusLabel changes THE tag SHALL draw and expose the new value at once, without a motion, and SHALL NOT announce the change by itself. |
TAG-13 | THE tag SHALL lay itself out inline with the text or the row it is placed in, as one unbreakable box, with the baseline of its label on the baseline of the text beside it; WHILE the text size is enlarged THE tag SHALL grow its container with its label, keeping the height of its size as a minimum, its paddings, and its glyph box and its dot at comp.tag.icon.size and comp.tag.dot.size. |
TAG-14 | WHERE the platform draws with a person's own forced colors (the web's forced-colors mode, and a platform's equivalent where it has one) THE tag SHALL draw an edge comp.tag.outline.width wide in the platform's text color inside its container in every variant, and its label, glyph and dot in that text color, so that a look whose fill the mode removes is still a bounded label; the status SHALL then rest on the label's words and statusLabel alone. |
TAG-15 | WHERE the layout direction is right-to-left THE tag SHALL mirror the order of its content and apply its paddings by logical start and end, so that the glyph or the dot sits at the right of the label. |
TAG-16 | THE tag SHALL take its layout direction from where it is used — the direction of the nearest ancestor that sets one, and the platform's own where none does — and SHALL have no direction setting of its own; WHEN that direction changes while the tag is shown THE tag SHALL draw itself for the new direction at once, without a motion of its own, keeping what it shows. |
TAG-17 | WHERE the layout direction is right-to-left THE tag SHALL draw the glyph of its icon slot mirrored left to right exactly when the system's icon set marks that glyph's name as mirrored or the product forces mirroring for that use, and unmirrored when the product forbids it: the icon helper mirrors the glyph inside its own box, about the box's vertical centre line, changing neither its place, size, color and fill nor the order TAG-15 gives. THE tag SHALL NOT mirror a glyph itself, and SHALL NOT mirror content the product gives as an image or a view of its own rather than by a glyph's name. The dot is never mirrored. |
TAG-18 | THE tag SHALL lay out its label as text of its own direction, isolated from the text around it: it takes the base direction of its first strong character, or the layout direction where it has none, so that a left-to-right word, a number with its sign or unit, a version and a date keep their own order in a right-to-left layout and reorder nothing beside them; THE tag SHALL still place the label by the layout direction, not by the text's own, and SHALL cut a label that does not fit (TAG-5) at the end of its own direction, so that a left-to-right label in a right-to-left layout loses its right end and never its beginning. |
TAG-19 | WHEN variant or size names a value that the active design system does not have, or status names a value this spec does not have, THE tag SHALL render with the default value (the default variant's or size's tokens, status default), and in debug builds report the unknown value. |
TAG-20 | IF label is empty THE tag SHALL draw nothing, take no space and expose nothing, and in debug builds report that a tag has no text: a glyph or a dot alone is not a tag. IF statusLabel is not empty while status is default THE tag SHALL ignore it and in debug builds report it. |
TAG-21 | WHILE disabled is true — the tag stands inside something disabled, and the component that holds it, or the product, says so — THE tag SHALL draw its fill, its label, its glyph and its dot from its look's disabled tokens (comp.tag.<variant>.disabled.container.color, comp.tag.<variant>.disabled.label.color and comp.tag.<variant>.disabled.icon.color, and their parts of each status), whatever its status, so that it fades with what it stands in and does not read as the one live part of a disabled whole; an outlined tag SHALL keep its edge and draw no fill. disabled SHALL change nothing else: the tag SHALL keep its size, its label and its place, take no input and no focus (TAG-9), and keep its text readable by assistive technology, which hears the disabled state from the element the tag stands in, never from the tag. WHERE the platform draws with a person's own forced colors THE tag SHALL draw its edge, its label, its glyph and its dot in the platform's color for disabled text (GrayText on the web) in place of its text color (TAG-14). |

| 備考 | <tanrei-tag> with the label as the label attribute and the glyph in the icon slot. The host is display: inline-flex with vertical-align: baseline and no role, no tabindex and no listeners; pointer-events stay as they are, so a press over a tag inside a link or a button reaches that element (TAG-10). statusLabel is reflected as the status-label attribute and drawn as visually hidden text before the label in the shadow root, followed by a comma and a space (TAG-11); the glyph and the dot are aria-hidden. The label is one dir="auto" run with text-overflow: ellipsis (TAG-18). Under forced-colors: active the container takes a CanvasText border of the outline width (TAG-14). disabled is a reflected boolean attribute that draws the look's disabled tokens and nothing else: no aria-disabled, no inert, no listener (TAG-21); under forced-colors: active the edge and the text are GrayText. | TanreiTag(_ title: String, variant:, status:, statusLabel:, size:, showsDot:, icon:), the glyph given by name through icon:. Not a Button and not focusable; allowsHitTesting(false) so a press reaches a row or a link that holds it. The view is one accessibility element whose label is statusLabel and the title joined by a comma, with the static text trait. isDisabled: (a parameter, not .disabled(_:), which would say the tag is a control): it draws the look's disabled tokens and changes nothing else (TAG-21). | TanreiTag(label, variant, status, statusDescription, size, showDot, icon), the glyph given by name through icon. No clickable and no focusable modifier. The label's text semantics are replaced by statusDescription and the label joined by a comma where a status label is given; the glyph and the dot are cleared from semantics. enabled is the inverse flag: it draws the look's disabled tokens and changes nothing else (TAG-21). | TanreiTag(label: …, variant:, status:, statusSemanticLabel:, size:, showDot:, icon:), the glyph given by name through icon. Wrapped in IgnorePointer, with no Focus. One Semantics(label:) over the drawn parts, which are excluded. enabled is the inverse flag: it draws the look's disabled tokens and changes nothing else (TAG-21). | <Tag label="Beta" />; the glyph is the icon prop (a glyph name). pointerEvents="none" and not focusable. One accessible element with accessibilityRole="text" whose accessibilityLabel is the status label and the label joined by a comma. Follows the app's direction where an ancestor's is not known. disabled: it draws the look's disabled tokens and changes nothing else (TAG-21). |

この 3 つは、何をするものかで区別します。
| 種類 | 何であるか | どこに置かれるか | 入力を受けるか |
|---|---|---|---|
| バッジ | ほかの要素に付くドットや数。 | アンカーの角の上。レイアウトの外です。 | 受けません。入力はアンカーに届きます。 |
| チップ | コントロール。 | レイアウトの中。 | 受けます。押す、切り替える、取り除くことができ、フォーカスと状態を持ちます。 |
| タグ | 静的なラベル。 | レイアウトの中、行内。 | 受けません。 |
- 押す、選ぶ、取り除くものは、チップです。どこかへ移動するものは、リンクです。
- 何かの上に載る数やドットは、バッジです。
- それが何であるか、どんな状態かを言葉で示すだけのものは、タグです。
ハンドラーを付けても、タグはコントロールになりません。リンク、ボタン、リスト項目、全体を押せる行の中では、タグはその要素のテキストのままです。タグの上での入力はその要素に届き、ホバー、フォーカス、押下はその要素が描きます。
variant |
描くもの | 用途 |
|---|---|---|
tonal（既定） |
控えめな塗り。 | ほとんどのタグ。 |
outlined |
塗りなしと 1 本の細い線。 | タグが密に並ぶ場所。表の列やカテゴリーの一覧など。 |
filled |
全面の塗り。 | 並んだ中で選ばれている 1 つ。複数の値のうちの既定値、項目のうちの必須など。見落とされてはならないステータスにも使います。 |
status は default、info、warning、error、success のいずれかです。変わるのは色だけです。枠線のタグは、どのステータスでもサーフェスの文字色と細い線のままなので、必ずドット（またはプロダクトが指定したグリフ）をステータスの色で描きます。ステータスが見えるのはその印だけだからです。
タグが自分でステータスのグリフを描くことはありません。役に立つ場所では、グリフを名前で指定します。このサイトのステータス表にある 6 つのステータスは、次のように描いています。
このサイトの 6 つのステータス
size |
高さ | 文字 | 用途 |
|---|---|---|---|
small |
20 | 12 | 入力欄のラベルの隣、表のセル、本文の行の中。行の高さを変えません。 |
medium（既定） |
24 | 14 | 見出しの隣、または単独で。 |
フィールドとフィールドグループの必須・任意のタグは、このコンポーネントの小さいサイズです。必須は Filled、任意は Tonal です。タグのトークンを読み、専用のトークンは持たないので、デザインシステムが小さなタグの見た目を変えれば、これらも一緒に変わります。
タグは自分の状態を持ちませんが、無効なものの中に置かれることがあります。無効なフィールドのラベル、リストの無効な行、メニューの無効な項目などです。disabled を付けると、ステータスにかかわらず、その見た目の無効の色（comp.tag.<variant>.disabled.*）で描かれ、包むものと一緒に薄くなり、そこだけが生きているようには見えません。ほかには何も変えません。タグの大きさと言葉はそのままで、入力もフォーカスも受けません。フィールドとフィールドグループは、無効の間、必須・任意のタグにこれを設定します。自分で作った無効な要素の中に置くタグには、利用者側で設定します。
通常のタグと、無効なものの中のタグ
- ステータスは言葉で伝えます。「失敗」ならそれで十分です。エラーの色で「ビルド 3 件」と表示するタグには
statusLabelが必要です。 - ラベルが収まる幅を確保します。収まらないラベルは省略記号で切られます。タグにはホバーもフォーカスもないので、残りを見せる手段がありません。
- 記事のカテゴリーのように 1 組のタグは、リスト（Web では
<ul>と<li>）に入れ、リストに名前を付けます。
- タグを押せるようにしない。押す、切り替える、取り除くラベルはチップで、どこかへ移動するものはリンクです。
- ラベルのないタグを使わない。ドットやグリフだけではタグになりません。何も描かれません。
- ステータスを色だけに頼らない。強制カラーモードでは、どのタグも文字色の縁とラベルになり、同じに見えます。
- アイコンに載せる数にタグを使わない。それはバッジです。
- ロール
none- ラベル付け
- The tag has no role and no name of its own: it is text, read where it sits. What is read is label, preceded by statusLabel where the tag has a status and the product gave one ("Error, 3 builds"). The glyph and the dot are decorative and hidden. Inside a link, a button, a list item or a table cell the tag's text is part of that element's content.
- 最小ターゲット
- 見た目のサイズが小さくても、ヒット領域は最小ターゲットサイズを満たします。 minimum 32px · pointer 44px · spacing 8px · touch 48px

備考
- Not interactive: the tag takes no input and no focus (TAG-9), so there is no target to size. minimumTarget holds trivially. A label that must be pressed, selected or removed is a chip; one that leads somewhere is a link.
- A status never rests on color alone (WCAG 1.4.1): the label says it ("Failed", "Stable"), or statusLabel adds it in words. The component cannot tell whether a label says its status, so this is the product's to check; the docs page says so with examples.
- Several tags in a row are the product's to group: where they are a set (an article's categories), the product lays them out in its platform's list semantics (ul and li on the web) and names the list. The tag does not group itself and has no list role.
- A tag does not announce a change of its text or status (TAG-12). Where a change must be announced (a build that finishes while the person watches), the product puts the tag in a live region or reports the change with a snackbar.
- A label cut by TAG-5 is still read in full by assistive technology, but a person who sees the ellipsis has no way to read the rest from the tag itself: it takes no hover and no focus. Give a tag room for its label, or let the element that holds it (a table cell, a list item) show the full text.
- Contrast in the default system: every label is a role drawn on its paired role (on-secondary-container on secondary-container, on-error-container on error-container, on-primary on primary, on-error on error, on-surface on a surface), each held to 4.5:1 by the token invariants. The status color used for a glyph or a dot keeps 3:1 against its status container and against every surface (it is held to 4.5:1 as text on surfaces). The outlined look's edge is decorative.
- Forced colors (TAG-14): a filled or tonal tag loses its fill, so every look gains an edge in the text color. Statuses then look alike, which is why the status must be in words.

- ロールも名前も持ちません。ラベルは、タグのある場所でテキストとして読まれます。リンク、ボタン、表のセルの中では、その要素の内容の一部になります。
statusLabelは、ラベルの前に別の語句として読まれます（「エラー、ビルド 3 件」）。描画はしません。statusがdefaultの間は無視します。- グリフとドットは支援技術から隠します。
- 入力もフォーカスも受けないので、フォーカスが止まる位置を増やさず、行の中に別のターゲットも作りません。
- 省略されたラベルも、全文が読まれます。
- 強制カラーモードでは、どの見た目にも文字色の縁が付き、ラベル、グリフ、ドットもその色になります。無効なタグは、無効な文字の色になります。
disabledは何も伝えません。無効であることは、タグが置かれた要素が伝えます。- 右から左のレイアウトでは、グリフやドットがラベルの右に移り、アイコンセットが指定するグリフは左右反転します。左から右のラベルは自身の語順を保ち、自身の末尾で切られます。
- 未知のバリアント、サイズ、ステータス、空のラベル、ステータスのない
statusLabelは、デバッグビルドで報告します。
- それぞれのタグの言葉がステータスを伝えているかを確かめます。「ビルド 3 件」が良い知らせか悪い知らせかは、コンポーネントには分かりません。
statusLabelはページの言語で書きます。disabledは、無効なものの中に置くタグにだけ設定し、その要素が無効であることを伝えているか（無効なコントロール、またはaria-disabled）を確かめます。薄くしたタグはそれを前提にしています。- ビルドが目の前で完了する場合のように、変化をその場で読み上げる必要があるときは、タグをライブリージョンに入れるか、スナックバーで知らせます。タグ自身は読み上げません。
