Combobox

A text input combined with a dropdown list of suggestions that filter as the user types.

Comboboxes let users type a value freely, pick from suggestions, or both. They're the right control when the list of options is long (countries, users, products) and exact typing alone would be slow. The ARIA `combobox` role formalizes the accessibility contract: input + listbox + selected option.

Also called

When to use

  • Selecting one item from a long list (search-with-suggestions)
  • Forms where users may type a known value or pick from a list
  • Tag inputs where users can add new values or pick existing

When not to use

  • Short option lists (3-6) where a segmented control or radio group is clearer
  • Free-text inputs with no suggestion list (use a plain text input)
