+A search input consists of a text field where users can type to find specific content or items. Unlike selects or dropdowns, which offer predefined options, a search input lets users enter their own keywords to filter or locate results. It includes a clear (×) button to easily remove the current input, allowing users to start a new search quickly.
+
+Use this when users need to search freely using their own terms — ideal for large or frequently changing sets of content.
+Do not use when the options are limited and known ahead of time — consider a dropdown or select instead

+
+The search input uses the [Combobox Pattern](https://www.w3.org/WAI/ARIA/apg/patterns/combobox/) recommendations from the WAI ARIA [Authoring Best Practices Guide (APG)](https://www.w3.org/WAI/ARIA/apg).
+
+When the dropdown is disabled it follows [WAI ARIA focusability recommendations](https://www.w3.org/WAI/ARIA/apg/practices/keyboard-interface/#focusabilityofdisabledcontrols) for composite widget elements, where dropdown items are still focusable even when the dropdown is disabled.
+
+#### Toggle and typeahead input
+
+When focus is on the toggle, the following keyboard interactions apply:
+
+| Key                    | Function                                                                               |
+| ---------------------- | -------------------------------------------------------------------------------------- |
+| <kbd>Down Arrow</kbd>  | Opens the listbox and moves focus to the first listbox item.                           |
+| <kbd>Tab</kbd>         | Moves focus to the close button if visible; otherwise, moves to the next focusable element, then closes the listbox.|
+| <kbd>Shift + Tab</kbd> | Moves focus out of element onto the previous focusable item and closes listbox.        |
+
+#### Listbox options
+
+Listbox options use the [APG's Roving tabindex](https://www.w3.org/WAI/ARIA/apg/practices/keyboard-interface/#kbd_roving_tabindex) recommendation. When focus is on the listbox, the following keyboard interactions apply:
+
+| Key                    | Function                                                                              |
+| ---------------------- | ------------------------------------------------------------------------------------- |
+| <kbd>Enter</kbd>       | Selects the options and closes the listbox.                                           |
+| <kbd>Space</kbd>       | Selects the options and closes the listbox.                                           |
+| <kbd>Tab</kbd>         | Moves focus out of element onto the next focusable options and closes listbox.        |
+| <kbd>Shift + Tab</kbd> | Moves focus to the toggle button and closes listbox.                                  |
+| <kbd>Up Arrow</kbd>    | Moves focus to the previous option, optionally wrapping from the first to the last.   |
+| <kbd>Down Arrow</kbd>  | Moves focus to the next option, optionally wrapping from the last to the first.       |
+| <kbd>Left Arrow</kbd>  | Returns focus to the combobox without closing the popup and moves the input cursor one character to the left. If the input cursor is on the left-most character, the cursor does not move.   |
+| <kbd>Right Arrow</kbd> | Returns focus to the combobox without closing the popup and moves the input cursor one character to the right. If the input cursor is on the right-most character, the cursor does not move.       |
+| <kbd>Escape</kbd>      | Close the listbox that contains focus and return focus to the input.          |
+| <kbd>Any letter</kbd>  | Navigates to the next option that starts with the letter.                             |
