Usage #

See it on NPM! How big is this package in your project?

yarn add @spectrum-web-components/combobox

Import the side effectful registration of <sp-combobox> via:

import '@spectrum-web-components/combobox/sp-combobox.js';

When looking to leverage the Combobox base class as a type and/or for extension purposes, do so via:

import { Combobox } from '@spectrum-web-components/combobox';

</sp-combobox>

Labeling #

A combobox must be labeled. Typically, you should render a visible label via <sp-field-label>. For exceptional cases, provide an accessible label via the label attribute.

<sp-field-label for="color">Color</sp-field-label>
<sp-combobox id="color">
    <sp-menu-item value="red">Red</sp-menu-item>
    <sp-menu-item value="green">Green</sp-menu-item>
    <sp-menu-item value="blue">Blue</sp-menu-item>
</sp-combobox>

Providing options #

Combobox options are presented as a popup menu. Menu items can be provided via markup as <sp-menu-item> children, or by assigning an array to the options property of an <sp-combobox>.

Options property #

Instead of providing <sp-menu-item> children, you can assign an array of ComboboxOptions to the options property, and <sp-combobox> will create matching menu items:

<sp-combobox id="color" label="Color"></sp-combobox>

<script>
    document.getElementById('color').options = [
        { value: "red", itemText: "Red" },
        { value: "green", itemText: "Green" },
        { value: "blue", itemText: "Blue" }
    ];
</script>

Dynamic options #

When you replace the options Array, or add/remove <sp-menu-item> children, the <sp-combobox> will detect that change and update its popup menu contents. For example, using Lit:

render() {
    return html`<sp-combobox label="Color" .options=${this.colorOptions}></sp-combobox>`;
}

mutate() {
    this.colorOptions = [
        ...this.colorOptions,
        { value: 'purple', itemText: 'Purple' }
    ];
}

Autocomplete #

The text in an <sp-combobox> is editable, and the string the user has typed in will become the value of the combobox unless the user selects a different value in the popup menu.

None #

autocomplete="none"

The suggested popup menu items will remain the same regardless of the currently-input value. Whenever the currently-typed input exactly matches the value of a popup menu item, that item is automatically selected.

List #

autocomplete="list"

The popup menu items are filtered to only those completing the currently-input value.

States #

Disabled #

<sp-field-label for="color">Color</sp-field-label>
<sp-combobox id="color" disabled>
    <sp-menu-item value="red">Red</sp-menu-item>

    <sp-menu-item value="blue">Blue</sp-menu-item>
</sp-combobox>

Pending #

<sp-field-label for="color">Color</sp-field-label>
<sp-combobox id="color" pending>
    <sp-menu-item value="red">Red</sp-menu-item>
    <sp-menu-item value="green">Green</sp-menu-item>
    <sp-menu-item value="blue">Blue</sp-menu-item>
</sp-combobox>

Focus and Accessibility #

The combobox supports both mouse and keyboard navigation. Mobile behavior is currently unspecified.

When an <sp-combobox> is focused, pressing the down arrow moves focus to the first menu item in the popup menu. The up and down arrows then move between available menu items.

The escape key dismisses the popup menu if open. Otherwise, it clears the combobox's textfield.

The enter key sets the value of the focused <sp-combobox>. If the popup menu is open, the value is set to the value of the selected menu item, returning focus back to the combobox's textfield.
