An input combined with a list of predefined items to select.
```svelte
{#snippet CheckIcon()}
{/snippet}
{#snippet XIcon()}
{/snippet}
{#snippet CaretDownIcon()}
{/snippet}
{@render XIcon()}
{@render CaretDownIcon()}
No fruits found.
{#snippet children(item: Fruit)}
{@render CheckIcon()}
{item.label}
{/snippet}
```
## Usage guidelines
- **Combobox is a filterable Select**: Use Combobox when the input is restricted to a set of predefined selectable items, similar to [Select](/components/select) but whose items are filterable using an input.

- **Avoid when not rendering an input**: Use [Select](/components/select) instead of Combobox if no input is being rendered, which includes accessibility features specific to a listbox without an input.
