# Select

[component-header:sl-select]

Selects allow you to choose one or more items from a dropdown menu.

```html preview
<sl-select>
  <sl-menu-item value="option-1">Option 1</sl-menu-item>
  <sl-menu-item value="option-2">Option 2</sl-menu-item>
  <sl-menu-item value="option-3">Option 3</sl-menu-item>
  <sl-menu-divider></sl-menu-divider>
  <sl-menu-item value="option-4">Option 4</sl-menu-item>
  <sl-menu-item value="option-5">Option 5</sl-menu-item>
  <sl-menu-item value="option-6">Option 6</sl-menu-item>
</sl-select>
```

?> This component doesn't work with standard forms. Use [`<sl-form>`](/components/form) instead.

## Examples

### Placeholders

Use the `placeholder` attribute to add a placeholder.

```html preview
<sl-select placeholder="Select one">
  <sl-menu-item value="option-1">Option 1</sl-menu-item>
  <sl-menu-item value="option-2">Option 2</sl-menu-item>
  <sl-menu-item value="option-3">Option 3</sl-menu-item>
</sl-select>
```

### Clearable

Use the `clearable` attribute to make the control clearable.

```html preview
<sl-select placeholder="Clearable" clearable>
  <sl-menu-item value="option-1">Option 1</sl-menu-item>
  <sl-menu-item value="option-2">Option 2</sl-menu-item>
  <sl-menu-item value="option-3">Option 3</sl-menu-item>
</sl-select>
```

### Pill

Use the `pill` attribute to give selects rounded edges.

```html preview
<sl-select pill>
  <sl-menu-item value="option-1">Option 1</sl-menu-item>
  <sl-menu-item value="option-2">Option 2</sl-menu-item>
  <sl-menu-item value="option-3">Option 3</sl-menu-item>
</sl-select>
```

### Disabled

Use the `disabled` attribute to disable a select.

```html preview
<sl-select placeholder="Disabled" disabled>
  <sl-menu-item value="option-1">Option 1</sl-menu-item>
  <sl-menu-item value="option-2">Option 2</sl-menu-item>
  <sl-menu-item value="option-3">Option 3</sl-menu-item>
</sl-select>
```

### Multiple

To allow multiple options to be selected, use the `multiple` attribute. It's a good practice to use `clearable` when this option is enabled. When using this option, `value` will be an array instead of a string.

```html preview
<sl-select placeholder="Select a few" multiple clearable>
  <sl-menu-item value="option-1">Option 1</sl-menu-item>
  <sl-menu-item value="option-2">Option 2</sl-menu-item>
  <sl-menu-item value="option-3">Option 3</sl-menu-item>
  <sl-menu-divider></sl-menu-divider>
  <sl-menu-item value="option-4">Option 4</sl-menu-item>
  <sl-menu-item value="option-5">Option 5</sl-menu-item>
  <sl-menu-item value="option-6">Option 6</sl-menu-item>
</sl-select>
```

### Grouping Options

Options can be grouped visually using menu labels and menu dividers.

```html preview
<sl-select placeholder="Select one">
  <sl-menu-label>Group 1</sl-menu-label>
  <sl-menu-item value="option-1">Option 1</sl-menu-item>
  <sl-menu-item value="option-2">Option 2</sl-menu-item>
  <sl-menu-item value="option-3">Option 3</sl-menu-item>
  <sl-menu-divider></sl-menu-divider>
  <sl-menu-label>Group 2</sl-menu-label>
  <sl-menu-item value="option-4">Option 4</sl-menu-item>
  <sl-menu-item value="option-5">Option 5</sl-menu-item>
  <sl-menu-item value="option-6">Option 6</sl-menu-item>
</sl-select>
```

### Sizes

Use the `size` attribute to change a select's size.

```html preview
<sl-select placeholder="Small" size="small" multiple>
  <sl-menu-item value="option-1">Option 1</sl-menu-item>
  <sl-menu-item value="option-2">Option 2</sl-menu-item>
  <sl-menu-item value="option-3">Option 3</sl-menu-item>
</sl-select>

<br>

<sl-select placeholder="Medium" size="medium" multiple>
  <sl-menu-item value="option-1">Option 1</sl-menu-item>
  <sl-menu-item value="option-2">Option 2</sl-menu-item>
  <sl-menu-item value="option-3">Option 3</sl-menu-item>
</sl-select>

<br>

<sl-select placeholder="Large" size="large" multiple>
  <sl-menu-item value="option-1">Option 1</sl-menu-item>
  <sl-menu-item value="option-2">Option 2</sl-menu-item>
  <sl-menu-item value="option-3">Option 3</sl-menu-item>
</sl-select>
```

### Selecting Options Programmatically

The `value` property is bound to the current selection. As the selection changes, so will the value. To programmatically manage the selection, update the `value` property.

```html preview
<div class="selecting-example">
  <sl-select placeholder="">
    <sl-menu-item value="option-1">Option 1</sl-menu-item>
    <sl-menu-item value="option-2">Option 2</sl-menu-item>
    <sl-menu-item value="option-3">Option 3</sl-menu-item>
  </sl-select>

  <br>

  <sl-button data-option="option-1">Set 1</sl-button>
  <sl-button data-option="option-2">Set 2</sl-button>
  <sl-button data-option="option-3">Set 3</sl-button>
</div>

<script>
  const container = document.querySelector('.selecting-example');
  const select = container.querySelector('sl-select');

  [...container.querySelectorAll('sl-button')].map(button => {
    button.addEventListener('click', () => {
      select.value = button.dataset.option; 
    });
  });
</script>
```

### Labels

Use the `label` attribute to give the select an accessible label. For labels that contain HTML, use the `label` slot instead.

```html preview
<sl-select label="Select one">
  <sl-menu-item value="option-1">Option 1</sl-menu-item>
  <sl-menu-item value="option-2">Option 2</sl-menu-item>
  <sl-menu-item value="option-3">Option 3</sl-menu-item>
</sl-select>
```

### Help Text

Add descriptive help text to a select with the `help-text` attribute. For help texts that contain HTML, use the `help-text` slot instead.

```html preview
<sl-select 
  label="Experience" 
  help-text="Please tell us your skill level."
>
  <sl-menu-item value="option-1">Novice</sl-menu-item>
  <sl-menu-item value="option-2">Intermediate</sl-menu-item>
  <sl-menu-item value="option-3">Advanced</sl-menu-item>
</sl-select>
```

### Prefix and Suffix

Use the `prefix` or `suffix` slot to add a prefix or suffix to the selected value

```html preview
<sl-select label="Sort by" class="sort">
  <sl-menu-item value="name.asc">Name (Asc)</sl-menu-item>
  <sl-menu-item value="name.desc">Name (Desc)</sl-menu-item>
  <sl-menu-item value="value.asc">Value (Asc)</sl-menu-item>
  <sl-menu-item value="value.desc">Value (Desc)</sl-menu-item>
  <sl-icon name="sort-down" slot="suffix"></sl-icon>
</sl-select>

<br>

<sl-select label="Transaction Price" class="price">
  <sl-icon name="currency-bitcoin" slot="prefix"></sl-icon>
  <sl-menu-item value="option-1">0.02</sl-menu-item>
  <sl-menu-item value="option-2">0.04</sl-menu-item>
  <sl-menu-item value="option-3">0.06</sl-menu-item>
</sl-select>

<style>
  sl-select.sort sl-icon {
    font-size: 24px;
  } 

  sl-select.price sl-icon {
    font-size: 24px;
  }   
</style>

<script>
  const select = document.querySelector('sl-select.sort');
  select.addEventListener('sl-change', event => {
    const icon = select.value.startsWith('name') ? 'sort-alpha-down' : 'sort-numeric-down';
    const variation = select.value.endsWith('asc') ? '' : '-alt';
    select.querySelector('sl-icon').name = `${icon}${variation}`;
  })
</script>
```
