Overview

Where the options live once a search field shares the popover.

In the plain select the listbox role sits on SelectContent itself. It cannot when a text field is in there too: a textbox is not an allowed child of a listbox, and axe reports aria-required-children — critical — for exactly that shape. shadcn's aria variant splits them the same way.

Classes are that variant's verbatim, except p-1 for its p-0: the padding this port keeps on the viewport moves here, because the viewport now holds the search field too.

def element_attributes(**defaults)
  # A named listbox, because an unnamed one is an
  # `aria-input-field-name` violation — serious, and WCAG rather than
  # best-practice. The dialog around it is named separately, so a
  # screen reader announces the popover and then the list rather than
  # the same words twice. shadcn's aria variant names both too.
