This component works with standard <form>
elements. Please refer to the section on
form controls to learn more about form submission and
client-side validation.
Examples
Labels
Use the label
attribute to give the select an accessible label. For labels that contain HTML,
use the label
slot instead.
<sl-select label="Select one">
<sl-option value="option-1">Option 1</sl-option>
<sl-option value="option-2">Option 2</sl-option>
<sl-option value="option-3">Option 3</sl-option>
</sl-select>
import SlOption from '@shoelace-style/shoelace/dist/react/option';
import SlSelect from '@shoelace-style/shoelace/dist/react/select';
const App = () => (
<SlSelect label="Select one">
<SlOption value="option-1">Option 1</SlOption>
<SlOption value="option-2">Option 2</SlOption>
<SlOption value="option-3">Option 3</SlOption>
</SlSelect>
);
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.
<sl-select label="Experience" help-text="Please tell us your skill level.">
<sl-option value="1">Novice</sl-option>
<sl-option value="2">Intermediate</sl-option>
<sl-option value="3">Advanced</sl-option>
</sl-select>
import SlOption from '@shoelace-style/shoelace/dist/react/option';
import SlSelect from '@shoelace-style/shoelace/dist/react/select';
const App = () => (
<SlSelect label="Experience" help-text="Please tell us your skill level.">
<SlOption value="1">Novice</SlOption>
<SlOption value="2">Intermediate</SlOption>
<SlOption value="3">Advanced</SlOption>
</SlSelect>
);
Placeholders
Use the placeholder
attribute to add a placeholder.
<sl-select placeholder="Select one">
<sl-option value="option-1">Option 1</sl-option>
<sl-option value="option-2">Option 2</sl-option>
<sl-option value="option-3">Option 3</sl-option>
</sl-select>
import SlOption from '@shoelace-style/shoelace/dist/react/option';
import SlSelect from '@shoelace-style/shoelace/dist/react/select';
const App = () => (
<SlSelect placeholder="Select one">
<SlOption value="option-1">Option 1</SlOption>
<SlOption value="option-2">Option 2</SlOption>
<SlOption value="option-3">Option 3</SlOption>
</SlSelect>
);
Clearable
Use the clearable
attribute to make the control clearable. The clear button only appears when
an option is selected.
<sl-select clearable value="option-1">
<sl-option value="option-1">Option 1</sl-option>
<sl-option value="option-2">Option 2</sl-option>
<sl-option value="option-3">Option 3</sl-option>
</sl-select>
import SlOption from '@shoelace-style/shoelace/dist/react/option';
import SlSelect from '@shoelace-style/shoelace/dist/react/select';
const App = () => (
<SlSelect placeholder="Clearable" clearable>
<SlOption value="option-1">Option 1</SlOption>
<SlOption value="option-2">Option 2</SlOption>
<SlOption value="option-3">Option 3</SlOption>
</SlSelect>
);
Filled Selects
Add the filled
attribute to draw a filled select.
<sl-select filled>
<sl-option value="option-1">Option 1</sl-option>
<sl-option value="option-2">Option 2</sl-option>
<sl-option value="option-3">Option 3</sl-option>
</sl-select>
import SlOption from '@shoelace-style/shoelace/dist/react/option';
import SlSelect from '@shoelace-style/shoelace/dist/react/select';
const App = () => (
<SlSelect filled>
<SlOption value="option-1">Option 1</SlOption>
<SlOption value="option-2">Option 2</SlOption>
<SlOption value="option-3">Option 3</SlOption>
</SlSelect>
);
Pill
Use the pill
attribute to give selects rounded edges.
<sl-select pill>
<sl-option value="option-1">Option 1</sl-option>
<sl-option value="option-2">Option 2</sl-option>
<sl-option value="option-3">Option 3</sl-option>
</sl-select>
import SlOption from '@shoelace-style/shoelace/dist/react/option';
import SlSelect from '@shoelace-style/shoelace/dist/react/select';
const App = () => (
<SlSelect pill>
<SlOption value="option-1">Option 1</SlOption>
<SlOption value="option-2">Option 2</SlOption>
<SlOption value="option-3">Option 3</SlOption>
</SlSelect>
);
Disabled
Use the disabled
attribute to disable a select.
<sl-select placeholder="Disabled" disabled>
<sl-option value="option-1">Option 1</sl-option>
<sl-option value="option-2">Option 2</sl-option>
<sl-option value="option-3">Option 3</sl-option>
</sl-select>
import SlOption from '@shoelace-style/shoelace/dist/react/option';
import SlSelect from '@shoelace-style/shoelace/dist/react/select';
const App = () => (
<SlSelect placeholder="Disabled" disabled>
<SlOption value="option-1">Option 1</SlOption>
<SlOption value="option-2">Option 2</SlOption>
<SlOption value="option-3">Option 3</SlOption>
</SlSelect>
);
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. To set multiple values at once, set
value
to a space-delimited list of values.
<sl-select label="Select a Few" value="option-1 option-2 option-3" multiple clearable>
<sl-option value="option-1">Option 1</sl-option>
<sl-option value="option-2">Option 2</sl-option>
<sl-option value="option-3">Option 3</sl-option>
<sl-option value="option-4">Option 4</sl-option>
<sl-option value="option-5">Option 5</sl-option>
<sl-option value="option-6">Option 6</sl-option>
</sl-select>
import SlOption from '@shoelace-style/shoelace/dist/react/option';
import SlSelect from '@shoelace-style/shoelace/dist/react/select';
const App = () => (
<SlSelect label="Select a Few" value="option-1 option-2 option-3" multiple clearable>
<SlOption value="option-1">Option 1</SlOption>
<SlOption value="option-2">Option 2</SlOption>
<SlOption value="option-3">Option 3</SlOption>
<SlOption value="option-4">Option 4</SlOption>
<SlOption value="option-5">Option 5</SlOption>
<SlOption value="option-6">Option 6</SlOption>
</SlSelect>
);
Note that multi-select options may wrap, causing the control to expand vertically. You can use the
max-options-visible
attribute to control the maximum number of selected options to show at
once.
Setting Initial Values
Use the value
attribute to set the initial selection.
When using multiple
, the value
attribute uses space-delimited values to
select more than one option. Because of this, <sl-option>
values cannot contain spaces.
If you’re accessing the value
property through Javascript, it will be an array.
<sl-select value="option-1 option-2" multiple clearable>
<sl-option value="option-1">Option 1</sl-option>
<sl-option value="option-2">Option 2</sl-option>
<sl-option value="option-3">Option 3</sl-option>
<sl-option value="option-4">Option 4</sl-option>
</sl-select>
import SlDivider from '@shoelace-style/shoelace/dist/react/divider';
import SlOption from '@shoelace-style/shoelace/dist/react/option';
import SlSelect from '@shoelace-style/shoelace/dist/react/select';
const App = () => (
<SlSelect value="option-1 option-2" multiple clearable>
<SlOption value="option-1">Option 1</SlOption>
<SlOption value="option-2">Option 2</SlOption>
<SlOption value="option-3">Option 3</SlOption>
</SlSelect>
);
Grouping Options
Use <sl-divider>
to group listbox items visually. You can also use
<small>
to provide labels, but they won’t be announced by most assistive devices.
<sl-select>
<small>Section 1</small>
<sl-option value="option-1">Option 1</sl-option>
<sl-option value="option-2">Option 2</sl-option>
<sl-option value="option-3">Option 3</sl-option>
<sl-divider></sl-divider>
<small>Section 2</small>
<sl-option value="option-4">Option 4</sl-option>
<sl-option value="option-5">Option 5</sl-option>
<sl-option value="option-6">Option 6</sl-option>
</sl-select>
import SlOption from '@shoelace-style/shoelace/dist/react/option';
import SlSelect from '@shoelace-style/shoelace/dist/react/select';
const App = () => (

<SlOption value="option-2">Option 2</SlOption>
<SlOption value="option-3">Option 3</SlOption>
<SlOption value="option-4">Option 4</SlOption>
<SlOption value="option-5">Option 5</SlOption>
<SlOption value="option-6">Option 6</SlOption>
</SlSelect>
);
Sizes
Use the size
attribute to change a select’s size. Note that size does not apply to listbox
options.
<sl-select placeholder="Small" size="small">
<sl-option value="option-1">Option 1</sl-option>
<sl-option value="option-2">Option 2</sl-option>

<SlOption value="option-2">Option 2</SlOption>
<SlOption value="option-3">Option 3</SlOption>
</SlSelect>
</>
);
Placement
The preferred placement of the select’s listbox can be set with the placement
attribute. Note
that the actual position may vary to ensure the panel remains in the viewport. Valid placements are
top
and bottom
.
<sl-select placement="top">
<sl-option value="option-1">Option 1</sl-option>
<sl-option value="option-2">Option 2</sl-option>
<sl-option value="option-3">Option 3</sl-option>
</sl-select>
import {
SlOption,
SlSelect
} from '@shoelace-style/shoelace/dist/react';
const App = () => (
<SlSelect placement="top">
<SlOption value="option-1">Option 1</SlOption>
<SlOption value="option-2">Option 2</SlOption>
<SlOption value="option-3">Option 3</SlOption>
</SlDropdown>
);
Prefix Icons
Use the prefix
slot to prepend an icon to the control.
<sl-select placeholder="Small" size="small" clearable>
<sl-icon name="house" slot="prefix"></sl-icon>
<sl-option value="option-1">Option 1</sl-option>
<sl-option value="option-2">Option 2</sl-option>
<sl-option value="option-3">Option 3</sl-option>
</sl-select>

<sl-option value="option-3">Option 3</sl-option>
</sl-select>
import SlIcon from '@shoelace-style/shoelace/dist/react/icon';
import SlOption from '@shoelace-style/shoelace/dist/react/option';
import SlSelect from '@shoelace-style/shoelace/dist/react/select';
const App = () => (
<>
<SlSelect placeholder="Small" size="small">
<SlIcon name="house" slot="prefix"></SlIcon>
<SlOption value="option-1">Option 1</SlOption>
<SlOption value="option-2">Option 2</SlOption>
<SlOption value="option-3">Option 3</SlOption>
</SlSelect>
<br />
<SlSelect placeholder="Medium" size="medium">
<SlIcon name="house" slot="prefix"></SlIcon>
<SlOption value="option-1">Option 1</SlOption>
<SlOption value="option-2">Option 2</SlOption>
<SlOption value="option-3">Option 3</SlOption>
</SlSelect>
<br />
<SlSelect placeholder="Large" size="large">
<SlIcon name="house" slot="prefix"></SlIcon>
<SlOption value="option-1">Option 1</SlOption>
<SlOption value="option-2">Option 2</SlOption>
<SlOption value="option-3">Option 3</SlOption>
</SlSelect>
</>
);
Custom Tags
When multiple options can be selected, you can provide custom tags by passing a function to the
getTag
property. Your function can return a string of HTML, a
Lit Template, or an
HTMLElement
. The getTag()
function will be called for each option. The first argument is an
<sl-option>
element and the second argument is the tag’s index (its position in the tag
list).
Remember that custom tags are rendered in a shadow root. To style them, you can use the
style
attribute in your template or you can add your own
parts and target them with the
::part()
selector.
<sl-select
placeholder="Select one"
value="email phone"
multiple
clearable
class="custom-tag"
>
<sl-option value="email">
<sl-icon slot="prefix" name="envelope"></sl-icon>
Email
</sl-option>
<sl-option value="phone">
<sl-icon slot="prefix" name="telephone"></sl-icon>
Phone
</sl-option>
<sl-option value="chat">
<sl-icon slot="prefix" name="chat-dots"></sl-icon>
Chat
</sl-option>
</sl-select>
<script type="module">
const select = document.querySelector('.custom-tag');
select.getTag = (option, index) => {
// Use the same icon used in the <sl-option>
const name = option.querySelector('sl-icon[slot="prefix"]').name;
// You can return a string, a Lit Template, or an HTMLElement here
return `
<sl-tag removable>
<sl-icon name="${name}" style="padding-inline-end: .5rem;"></sl-icon>
${option.getTextLabel()}
</sl-tag>
`;
};
</script>
Be sure you trust the content you are outputting! Passing unsanitized user input to
getTag()
can result in XSS vulnerabilities.
