# ModelSelector

Disclosure-backed model/provider picker for the prompt composer (native <details>).

[All components](https://rickylabs.github.io/netscript/design-system/components/) · [Theme builder](https://rickylabs.github.io/netscript/create/) · [Implementation source](https://github.com/rickylabs/netscript/blob/main/packages/fresh-ui/registry/components/ui/model-selector.tsx)

## Live preview

[Open live model-selector preview](https://rickylabs.github.io/netscript/assets/fresh-ui/preview/?component=model-selector&theme=studio-utility)

## Install

```bash
netscript ui:add model-selector
```

## Usage and examples

The preview runs this JSX with the installed components. Import any composed primitives from your UI directory.

```tsx
import { useState } from 'preact/hooks';
import { ModelSelector } from '@app/components/ui/model-selector.tsx';

export function Example() {
  const [value, setValue] = useState('standard');
  const [open, setOpen] = useState(false);
  const [notice, report] = useState('');
  return (<><div><ModelSelector value={value} models={[{id:"standard",label:"Standard"},{id:"fast",label:"Fast"}]} onChange={setValue} /></div><p role="status">{notice}</p></>);
}
```

## Props

Generated from native `deno doc --json --private` over the shipped implementation. Compound component props retain their owning interface; native attributes pass through where declared.

| Owner | Prop | Type | Optional | Description |
| --- | --- | --- | --- | --- |
| `ModelSelectorProps` | `value` | `string` | No | Selected model id. |
| `ModelSelectorProps` | `models` | `ModelOption[]` | No | Available models. |
| `ModelSelectorProps` | `onChange` | `(id: string) => void` | Yes | Invoked with the chosen model id. |
| `ModelSelectorProps` | `align` | `"left" \| "right"` | Yes | Menu alignment relative to the trigger. |
| `ModelSelectorProps` | `class` | `string` | Yes |  |

```typescript
ModelSelectorProps extends Omit<JSX.DetailsHTMLAttributes<HTMLDetailsElement>, "class" | "onChange">
```

## Keyboard

| Key | Action |
| --- | --- |
| `Enter/Space` | Toggle summary or activate an option button |
| `Tab` | Move through native option buttons |

## Contract and compatibility

Accessibility pattern: native disclosure and option buttons

- Native DOM attributes pass through where the implementation accepts them.
- Native details is the disclosure; the listbox role does not add roving arrow-key behavior.

Design contract values marked planned are not implementation props. The props above describe what ships today.
