Chip

A chip is used to communicate a value or a set of attribute-value pairs within workflows that involve filtering a set of objects.

Accessibility

To implement an accessible PatternFly chip component:

Testing

At a minimum, a chip should meet the following criteria:

  • Tab navigates to the next chip close button or focusable element, and Shift + Tab navigates to the previous chip close button or focusable element.
  • Enter and Space should be able to activate the chip close button. This can usually be achieved by using "click" events.
  • This can be achieved by ensuring the chip component itself has the tabindex="0" attribute. A chip should then be included in the standard keyboard navigation.
  • Follow the tooltip accessibility documentation.

React customization

The following React props have been provided for more fine-tuned control over accessibility.

Prop
Applied to
Reason
closeBtnAriaLabel="[text describing the close button]"
Chip
Adds an accessible name to the chip's close button. Required.

When passing in a custom value, you do not need to repeat the chip's content and should only include a verb such as "close" or "remove".
component="[element tag]"
Chip
Sets the base element for the chip (div element by default).

When using a chip as an overflow chip, or in any manner where clicking the chip itself causes an action to trigger, the value passed in should be "button" to provide the built-in interaction necessary for improved accessibility.

HTML/CSS customization

The following HTML attributes and PatternFly classes can be used for more fine-tuned control over accessibility.

Attribute or class
Applied to
Reason
id
.pf-c-chip
The value of this attribute is passed into the close button's aria-labelledby attribute. Required when a chip has a close button.
aria-label="[text describing the close button]"
.pf-c-chip > button
Adds an accessible name to the chip's close button. Required when the close button does not contain any visible text.
aria-labelledby="[space separated list of the chip's and close button's ID]"
.pf-c-chip > button
Combines the accessible name of the close button and the chip content, providing more context to users regarding which chip will be closed. Required.
id
.pf-c-chip > button
The value of this attribute is passed into the close button's aria-labelledby attribute. Required.
aria-hidden="true"
.pf-c-chip > button > i
Removes the close button icon from the accessibility tree, preventing assistive technologies from potentially announcing duplicate or unnecessary information without visually hiding it. Required if the close button contains an icon.
