# Select icon
Icons describe the type of input a select requires. They can also be interaction targets.
## Basic usage
### HTML structure
```html
<i class="material-icons mdc-select__icon" tabindex="0" role="button">event</i>
```
#### Icon set
We recommend using [Material Icons](https://material.io/tools/icons/) from Google Fonts:
```html
<head>
<link rel="stylesheet" href="https://fonts.googleapis.com/icon?family=Material+Icons">
</head>
```
However, you can also use SVG, [Font Awesome](https://fontawesome.com/), or any other icon library you wish.
### JavaScript instantiation
```js
import {MDCSelectIcon} from '@material/select/icon';
const icon = new MDCSelectIcon(document.querySelector('.mdc-select__icon'));
```
## Variants
Leading icons can be applied to default or `mdc-select--outlined` Selects. To add a leading icon, add the class `mdc-select--with-leading-icon` to the root element, add an `i` element with your preferred icon as a child of the `mdc-select__anchor` element, and give it a class of `mdc-select__icon`.
> **NOTE:** if you would like to display un-clickable icons, simply omit `tabindex="0"` and `role="button"`, and the CSS will ensure the cursor is set to default, and that interacting with an icon doesn't do anything unexpected.
### Leading icon
> **NOTE:** when using leading icons in select anchor, also include an empty `<span class="mdc-deprecated-list-item__graphic"></span>` in each list item.
In filled select:
```html
<div class="mdc-select mdc-select--filled mdc-select--with-leading-icon">
<div class="mdc-select__anchor">
<span class="mdc-select__ripple"></span>
<span class="mdc-floating-label">Pick a Food Group</span>
<i class="material-icons mdc-select__icon" tabindex="0" role="button">event</i>
...
</div>
<div class="mdc-select__menu mdc-menu mdc-menu-surface mdc-menu-surface--fullwidth">
<ul class="mdc-deprecated-list" role="listbox">
<li class="mdc-deprecated-list-item mdc-deprecated-list-item--selected" aria-selected="true" role="option" data-value="grains">
<span class="mdc-deprecated-list-item__ripple"></span>
<span class="mdc-deprecated-list-item__graphic"></span>
<span class="mdc-deprecated-list-item__text">Bread, Cereal, Rice, and Pasta</span>
</li>
<li class="mdc-deprecated-list-item" role="option" data-value="vegetables">
<span class="mdc-deprecated-list-item__ripple"></span>
<span class="mdc-deprecated-list-item__graphic"></span>
<span class="mdc-deprecated-list-item__text">Vegetables</span>
</li>
<li class="mdc-deprecated-list-item" role="option" data-value="fruit">
<span class="mdc-deprecated-list-item__ripple"></span>
<span class="mdc-deprecated-list-item__graphic"></span>
<span class="mdc-deprecated-list-item__text">Fruit</span>
</li>
</ul>
</div>
```
In outlined select:
```html
<div class="mdc-select mdc-select--outlined mdc-select--with-leading-icon">
<div class="mdc-select__anchor">
<span class="mdc-notched-outline">
...
</span>
<i class="material-icons mdc-select__icon" tabindex="0" role="button">event</i>
...
</div>
<!-- The rest of the select markup, see above. -->
</div>
```
