import { Meta, Story, Primary, Controls, Canvas } from "@storybook/addon-docs";
import * as stories from "./chip-select.stories";
<Meta of={stories} />
```ts
import { ChipSelectComponent } from "@bitwarden/components";
```
# Chip Select
`<bit-chip-select>` is a select element that is commonly used to filter items in lists or tables.
<Canvas>
<Story of={stories.Default} />
</Canvas>
## Options
Options are passed to the select via an `options` input.
```ts
@Component({
selector: `
<bit-chip-select options=[options]></bit-chip-select>
`,
})
class MyComponent {
protected options = [
{
label: "Foo",
value: "foo",
icon: "bwi-folder",
},
{
label: "Bar",
value: "bar",
icon: "bwi-exclamation-triangle tw-text-danger",
},
{
label: "Baz",
value: "baz",
disabled: true,
},
];
}
```
### Option Trees
Nested trees of options are also supported by passing an array of options to `children`.
```ts
const options = [
{
label: "Foo0",
value: "foo0",
icon: "bwi-folder",
children: [
{
label: "Foo1",
value: "foo1",
icon: "bwi-folder",
children: [
{
label: "Foo2",
value: "foo2",
icon: "bwi-folder",
children: [
{
label: "Foo3",
value: "foo3",
},
],
},
],
},
],
},
{
label: "Bar",
value: "bar",
icon: "bwi-folder",
},
{
label: "Baz",
value: "baz",
icon: "bwi-folder",
},
];
```
<Canvas>
<Story of={stories.NestedOptions} />
</Canvas>
## Placeholder Content
Placeholder content is shown when no item is selected.
```html
<bit-chip-select placeholderText="Foo" placeholderIcon="bwi-key"> </bit-chip-select>
```
## Reading the current value
The component implements `ControlValueAccessor`, so the current selected value can be read via
`ngModel` or `[formControlName]`.
```html
<bit-chip-select [(ngModel)]="..."></bit-chip-select>
```
