Named slots

  <div slot="prepend" />
  <div slot="selection" let:selection let:index /> <!-- index only available when multiple -->
  <div slot="clear-icon" />  
  <div slot="multi-clear-icon" />  
  <div slot="loading-icon" />  
  <div slot="chevron-icon" /> 
  <div slot="list-prepend" />  
  <div slot="list" let:filteredItems />  
  <div slot="list-append" />  
  <div slot="item" let:item let:index />  
  <div slot="input-hidden" let:value />
  <div slot="required" let:value />
  <!-- Remember you can also use `svelte:fragment` to avoid a container DOM element. -->
  <svelte:fragment slot="empty" />  


Event Name Callback Description
change { detail } fires when the user selects an option
input { detail } fires when the value has been changed
focus { detail } fires when select > input on:focus
blur { detail } fires when select > input on:blur
clear { detail } fires when clear is invoked or item is removed (by user) from multi select
loaded { options } fires when loadOptions resolves
error { type, details } fires when error is caught
filter { detail } fires when listOpen: true and items are filtered
hoverItem { detail } fires when hoverItemIndex changes


items can be simple arrays or collections.

  import Select from 'svelte-select';

  let simple = ['one', 'two', 'three'];

  let collection = [
    { value: 1, label: 'one' },
    { value: 2, label: 'two' },
    { value: 3, label: 'three' },

<Select items={simple} />

<Select items={collection} />

They can also be grouped and include non-selectable items.

  import Select from 'svelte-select';

  const items = [
    {value: 'chocolate', label: 'Chocolate', group: 'Sweet'},
    {value: 'pizza', label: 'Pizza', group: 'Savory'},
    {value: 'cake', label: 'Cake', group: 'Sweet', selectable: false},
    {value: 'chips', label: 'Chips', group: 'Savory'},
    {value: 'ice-cream', label: 'Ice Cream', group: 'Sweet'}

  const groupBy = (item) =>;

<Select {items} {groupBy} />

You can also use custom collections.

  import Select from 'svelte-select';

  const itemId = 'id';
  const label = 'title';

  const items = [
    {id: 0, title: 'Foo'},
    {id: 1, title: 'Bar'},

<Select {itemId} {label} {items} />

Async Items

To load items asynchronously then loadOptions is the simplest solution. Supply a function that returns a Promise that resolves with a list of items. loadOptions has debounce baked in and fires each time filterText is updated.

  import Select from 'svelte-select';

  import { someApiCall } from './services';

  async function examplePromise(filterText) {
    // Put your async code here...
    // For example call an API using filterText as your search params
    // When your API responds resolve your Promise
    let res = await someApiCall(filterText);
    return res;

<Select loadOptions={examplePromise} />

Advanced List Positioning / Floating

svelte-select uses floating-ui to control the list floating. See their docs and pass in your config via the floatingConfig prop.

  import Select from 'svelte-select';

  let floatingConfig = {
    strategy: 'fixed'

<Select {floatingConfig} />

Exposed methods

These internal functions are exposed to override if needed. Look through the test file (test/src/index.js) for examples.

export let itemFilter = (label, filterText, option) => label.toLowerCase().includes(filterText.toLowerCase());
export let groupBy = undefined;
export let groupFilter = groups => groups;
export let createGroupHeaderItem = groupValue => {
  return {
    value: groupValue,
    label: groupValue
export function handleClear() {
  value = undefined;
  listOpen = false;
  dispatch("clear", value);
export let loadOptions = undefined; // if used must return a Promise that updates 'items'
/* Return an object with { cancelled: true } to keep the loading state as active. */
export const getFilteredItems = () => {
  return filteredItems;
export let debounce = (fn, wait = 1) => {
  timeout = setTimeout(fn, wait);

Override core functionality at your own risk! See (get-items.js & filter.js)

    // core replaceable methods...

A11y (Accessibility)

Override these methods to change the aria-context and aria-selection text.

export let ariaValues = (values) => {
  return `Option ${values}, selected.`;

export let ariaListOpen = (label, count) => {
  return `You are currently focused on option ${label}. There are ${count} results available.`;

export let ariaFocused = () => {
  return `Select is focused, type to refine list, press down to open the menu.`;

CSS custom properties (variables)

You can style a component by overriding the available CSS custom properties.

  import Select from 'svelte-select';

<Select --border-radius= "10px" --placeholder-color="blue" />

You can also use the inputStyles prop to write in any override styles needed for the input.

  import Select from 'svelte-select';

  const items = ['One', 'Two', 'Three'];

<Select {items} inputStyles="box-sizing: border-box;"></Select>

๐Ÿงช Experimental: Replace styles (Tailwind, Bootstrap, Bulma etc)

If you'd like to supply your own styles use: import Select from 'svelte-select/no-styles/Select.svelte'. Then somewhere in your code or build pipeline add your own. There is a tailwind stylesheet via import 'svelte-select/tailwind.css'. It uses @extend so PostCSS is required.
