Angular Material Chips

The md-chips is an angular directive used as a special component called a chip. It is used to represent a small set of information, for example, a contact, tag, etc. A custom template can be used to render the contents of a chip. It can be achieved by specifying the md-chip-template element containing the custom content as md-chips. The <mat-chip-list> displays a list of values as individual, keyboard accessible, chips.

Unstyled chips

By default, content design styles are implemented in <mat-chip>. For any styled chip, do not use <mat-basic-chip>. We can optimize chip appearance by implementing CSS.

<mat-basic-chip> gets the mat-basic-chip CSS class in addition to the mat-chip-class.


The chips are selected through the selected property. It can be disabled by selecting to select on <mat-chip-list>.

Whenever the state of the selection changes, a chipselectionchange is emitted through the event (selection change).

Disabled chips

Individual chips will be disabled by implementing the Disabled attribute on the chip. When disabled, chips are neither selectable nor noticeable.

Chip Input

The MatChipInput directive will be used with a chip list to streamline the interaction between the two components. The directive adds chip-specific behaviour to the input element within <mat-form-field> to add and remove the chip. With MatChipInput <input> will be placed inside or outside the chip-list element.

Keyboard interaction

Users can move by the chips using the arrow keys and select /deselect them with space. Clicking also focuses on the chips, ensuring that keyboard navigation begins on the appropriate chip.


If you want the chips in the list to be stacked vertically, instead of horizontally, you can apply the mat-chip-list-stacked class, as well as the aria-orientation=”vertical” attribute:

Specifying global configuration defaults

Default options for the chips module can be specified using the MAT_CHIPS_DEFAULT_OPTIONS injection token.


The selected color of a <mat-chip> can be changed by using the color property. By default, chips use a neutral background color depending on the current theme (light or dark). It can be changed to ‘Primary,’ ‘accent’ or ‘Warn’.


A chip-list behaves as a role = “listbox”, with each chip having a role = “option”. The chip input must contain a placeholder or be given a meaningful label via area-label or area-labeledby.
