# field.filter

Narrows a list that is already shown, usually in a toolbar: "Search this feed"

Component: [`<Field>`](https://www.prongs.dev/docs/components/field.md) · Renders: `<input type="search">` · Profile: [UI](https://www.prongs.dev/docs/intents/ui.md)

## Example

```tsx
<Field intent="field.filter" id="filter" name="filter" />
```

## Choosing between neighbours

Find the row that describes your element, and use the intent on the right.

| If it is for… | Use |
|---|---|
| Narrows a list that is already shown, usually in a toolbar: "Search this feed" | `field.filter` (this page) |
| Narrowing a list that is already shown (rather than [`field.search`](https://www.prongs.dev/docs/intents/field/search.md)) | `field.filter` (this page) |

## Connections

Declared in the registry, both directions. Where an intent is used in your own code is something check and the gallery see; this site has no app code.

## For registry authors

**Starter intents.** These are the intents `prongs add` puts in your registry, shown in this site’s theme. Yours are your own `registry.ts`: rename, restyle and add to them, and see them with `prongs add gallery`.

What this intent is built from and its entry in `components/prongs/registry.ts`. You only need this to change how it looks or to add an intent like it.

How field.filter resolves, and its definition

Each layer adds to the one before it; a later class wins over an earlier one that sets the same thing.

- [`input.default`](https://www.prongs.dev/docs/intents/ui.md#input-default) — Bordered input box

  placeholder:text-muted-foreground focus-visible:outline-none
  focus-visible:ring-2 focus-visible:ring-ring
  disabled:cursor-not-allowed disabled:opacity-50
  aria-invalid:border-destructive
  ```
