# ComboboxTrigger

Source: `client/lib/theme/vueda-tailwind/controls/index.js`

> The pressable surface that opens the [ComboboxList.root](/v3/reference/theming/keys/ComboboxList.md#theme-key-ComboboxList-root). Ships empty today: in-tree consumers (`WidgetCombobox`) supply their own input-shell chrome via `asChild`, so the bare primitive has no usable default. The Combobox-vs-Select differentiator (Combobox reads as a field because the user is about to type) is enforced by consumers, not by this slot. Giving the bare primitive an input-shell default is deferred until the same session settles the multi-select div-trigger pattern, since one API choice covers both.
