  • Never intermingle default and link tags.
  • Never use a link tag to trigger interactions other than navigating to other pages or additional information. Instead, use a Button.
  • Link tags can be used to allow users to navigate to view other objects which are similarly labelled.

    </button>
</div>
<mds-tag dismissible=true>Equity</mds-tag>
  • The dismissal action is tied only to the remove-s icon within the tag.
  • Dismissible tags can be used to represent removable filtering criteria.
Do use only default, or only dismissible tags within a single group.

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.

Don‘t display small and medium tags together in the same set.

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

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”.

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

Prop Type Validation Default Description

class

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 a Boolean set to false

false

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

dismissIcon

String

––

<mds-icon name="remove--s"></mds-icon>

Allows alternate icon markup to be passed within a dismissible tag.

href

String, Boolean

––

false

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

id

String

––

––

The id attribute for the HTML element.

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

Enum: ["small", "medium"]

small

Alters the size of the tag.

text

String

Required

––

Sets the text that appears within the tag. Text can also be set using the default slot. If text is set via the default slot AND via the text prop, the text prop wins.
  • Use kebab-case when setting props in HTML. For example, dismissIcon would be written as dismiss-icon.
Slots

Any text passed in between the <mds-tag></mds-tag> tags will be used as the tag's content. This slot can only accept plain text. If no content is passed in via the slot and the text prop is empty, the tag's text will be "undefined".

Methods
Method Name Description

dismiss(removeAfterDismissal = this.removable || true)

This is the same method called internally when the dismiss “X” on the tag is clicked. May be useful for a Product to querySelectorAll(‘.mds-tag’) and programatically call dismiss() on each of them based on some other interaction besides a user clicking the “X” 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

Creating a tag and making it dismissible:

<!-- Using Props -->
<mds-tag text="Components" dismissible="true"></mds-tag>
<!-- Using Slots -->
<mds-tag dismissible="true"> Components </mds-tag>

Making a tag a link and setting its size: 

<!-- Using Props -->
<mds-tag text="Quantitative Research" href="/quant-research.html" size="medium"></mds-tag>
<!-- Using Slots -->
<mds-tag href="/quant-research.html" size="medium"> Quantitative Research </mds-tag>

Tag Group

Props

Prop Type Validation Default Description

class

String

––

––

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

content

String

Required

––

Accepts a string of HTML that will override the default slot.

id

String

––

––

The id attribute for the HTML element.

Slots

Pass two or more <mds-tag> elements between the <mds-tag-group></mds-tag-group> to set the content of the tag group. This slot can be overridden using the content prop.

Usage Examples

Creating a group of link tags:

<!-- Using Props -->
<mds-tag-group content='<mds-tag href="#"> Quantitative Research </mds-tag> <mds-tag href="#"> Global </mds-tag> <mds-tag href="#"> Asset Manager </mds-tag>'></mds-tag-group>
<!-- Using Slots -->
<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.
