CSS contract table

Style the primitive root and the projected chip markup directly in your template. No ::ng-deep is needed because the chip body belongs to you.

SelectorApplied onPurpose
[data-slot="chips"]Root shellStable hook for root layout, spacing, and any shell treatment you want to add.
[data-slot="chip"]Projected chip itemStable hook for the pill shell when you prefer attribute selectors over explicit classes.
[data-slot="chip-remove"]Projected remove controlStable hook for remove-button layout, hover, and focus styling.
[data-disabled]Root, chip, remove controlShared disabled-state hook reflected from the primitive contracts.
[data-focused]Remove controlFocus hook on the remove button so you can draw a local ring without extra scripting.

State selectors

The primitive reflects stable slots and focus hooks, so you can style the list, chip, and remove button without owning extra state.

Release owner shell

The primitive root stays quiet while your projected chip classes carry the visible presentation.
