Sizing

Sizing affects text size and internal padding. The default size is small, and you can use modifier classes or props to make the tag smaller or larger.

Use When

  • Showing information which helps a user make sense of content on the page, such as filter parameters or object metadata.

Don′t Use When

  • Creating an object whose primary function is triggering an interaction. Instead, use a Button.
  • Offering a description of an object that exceeds 3–5 words. Instead, consider using a Tooltip or Popover.

Visual Language

Diagram of space applied between a tag and other content.

Behaviors

  • When removed, fade the tag out and relinquish its space. Remaining tags should then fill the space as appropriate.

Editorial

  • Strive for short tag labels that clearly describe an action.
  • Use title case and capitalize prepositions of four letters or more.
  • Avoid tag labels longer than three to five words, particularly in responsive settings.
  • Always use consistent naming when using a tag to represent a parameter set somewhere else, i.e., if the filter setting is “Equity” the tag should read “Equity”.

CSS

Class References

Class
Applies to
Outcome

mds-tag--medium

mds-tag

Increases text size and internal padding.

mds-tag--link

mds-tag

Adds Link styling to tag text.

mds-tag--is-dismissed

mds-tag

Dismisses the alert by animating a fade-out effect.

mds-tag-group

<div>

Initializes a wrapping container to properly space a group of tags.

Web Component

Tags are comprised of two separate web components, each with a dedicated API:

  • Tag - Renders the tag component and offers props for all offered variations and behaviors.
  • Tag Group - Wraps multiple <mds-tag> elements to present them as a group.

Tag

Props

When setting props as attributes on a custom HTML element, use kebab-case instead of camelCase.

Prop
Type
Validation
Default
Description

additionalClass

String

A space-separated list of class names that will be appended to the default mds-tag class.

dismissible

Boolean

Only valid when href is not set

false

If true, renders a dismissibile tag. Link tags cannot be made dismissible.

dismissIconAriaLabel

String

Dismiss

Sets the aria-label attribute on the icon-only dismiss button.

href

String, Boolean

false

This switches the parent element for the tag from a <div> (default) to an <a>. When included, dismissible is ignored.

removable

Boolean

Only valid when dismissible is set to true

true

When true, removes the Tag from the DOM after the dismiss animation completes. If false, Tag is simply hidden when dismissed, not removed.

size

String

One of: small, medium

small

Alters the size of the tag.

text

String

Required

The text for the tag. Can also be passed via the default slot.

Slots

Pass text in between the <mds-tag></mds-tag> tags to set the tag's text content. This can be overridden with the text prop.

Methods

Method Name
Description

dismiss(removeAfterDismissal = this.removable || true)

This is the same method called internally when the dismiss button on the tag is clicked. Product teams may find it useful to querySelectorAll('.mds-tag') and programatically call dismiss() on each of them based on an interaction besides a user clicking the dismiss button on the tag itself.

Events

Event Name
Description

mds-tag-dismissed

If dismissible is set to true, the tag will trigger an mds-tag-dismissed custom event after the tag has visibly disappeared.

mds-tag-removed

If removable is set to true, the tag will trigger an mds-tag-removed custom event after the tag has been removed from the DOM.

Usage Examples

Setting text and dismissible via props:

<mds-tag text="Components" dismissible></mds-tag>

Setting href and size via props. Using the default slot for text content:

<mds-tag href="/quant-research.html" size="medium"> Quantitative Research </mds-tag>

Tag Group

Props

When setting props as attributes on a custom HTML element, use kebab-case instead of camelCase.

Prop
Type
Validation
Default
Description

additionalClass

String

A space-separated list of class names that will be appended to the default mds-tag-group class.

Slots

Pass two or more <mds-tag> elements between the <mds-tag-group></mds-tag-group> to set the content of the tag group.

Usage Examples

Using the default slot for the tags in the group:

<mds-tag-group>
    <mds-tag href="#"> Quantitative Research </mds-tag>
    <mds-tag href="#"> Global </mds-tag>
    <mds-tag href="#"> Asset Manager </mds-tag>
</mds-tag-group>

Implementation

  • Always use an Icon-Only Button for the dismiss action on a dismissible tag. This provides the required keyboard navigability.

Best Practices

  • Always include a title tag on the dismiss icon with appropriate text for screen readers like “Remove Tag” or “Dismiss Tag.” See the accessibility guidelines for MDS icons for more information.
