Class: Shadcn::Select::Empty::Component

Inherits:
ApplicationViewComponent show all
Defined in:
app/components/shadcn/select/empty/component.rb

Overview

Shown when the filter matches nothing.

A sibling of the listbox rather than a child of it. shadcn's aria variant nests its empty state inside the list and gives it role="option" — an option that cannot be chosen — which is how React Aria's collection renders one. Outside the list the question does not arise, and a non-option inside a listbox is precisely the shape axe rejected while this component's structure was being chosen.

The classes are this gem's own. Upstream's are a single cn-select-empty-aria, defined across the themed sheets in registry/styles/, which this gem does not ship.
