Examples

Prefix & Suffix

Add content to the start and end of menu items using the prefix and suffix slots.

<sl-menu style="max-width: 200px;">
  <sl-menu-item>
    <sl-icon slot="prefix" name="house"></sl-icon>
    Home
  </sl-menu-item>

  <sl-menu-item>
    <sl-icon slot="prefix" name="envelope"></sl-icon>
    Messages
    <sl-badge slot="suffix" variant="primary" pill>12</sl-badge>
  </sl-menu-item>

  <sl-divider></sl-divider>

  <sl-menu-item>
    <sl-icon slot="prefix" name="gear"></sl-icon>
    Settings
  </sl-menu-item>
</sl-menu>

{% raw %}

import SlBadge from '@onsonr/nebula/dist/react/badge';
import SlDivider from '@onsonr/nebula/dist/react/divider';
import SlIcon from '@onsonr/nebula/dist/react/icon';
import SlMenu from '@onsonr/nebula/dist/react/menu';
import SlMenuItem from '@onsonr/nebula/dist/react/menu-item';

const App = () => (
  <SlMenu style={{ maxWidth: '200px' }}>
    <SlMenuItem>
      <SlIcon slot="prefix" name="house" />
      Home
    </SlMenuItem>

    <SlMenuItem>
      <SlIcon slot="prefix" name="envelope" />
      Messages
      <SlBadge slot="suffix" variant="primary" pill>
        12
      </SlBadge>
    </SlMenuItem>

    <SlDivider />

    <SlMenuItem>
      <SlIcon slot="prefix" name="gear" />
      Settings
    </SlMenuItem>
  </SlMenu>
);

{% endraw %}

Disabled

Add the disabled attribute to disable the menu item so it cannot be selected.

<sl-menu style="max-width: 200px;">
  <sl-menu-item>Option 1</sl-menu-item>
  <sl-menu-item disabled>Option 2</sl-menu-item>
  <sl-menu-item>Option 3</sl-menu-item>
</sl-menu>

{% raw %}

import SlMenu from '@onsonr/nebula/dist/react/menu';
import SlMenuItem from '@onsonr/nebula/dist/react/menu-item';

const App = () => (
  <SlMenu style={{ maxWidth: '200px' }}>
    <SlMenuItem>Option 1</SlMenuItem>
    <SlMenuItem disabled>Option 2</SlMenuItem>
    <SlMenuItem>Option 3</SlMenuItem>
  </SlMenu>
);

{% endraw %}

Loading

Use the loading attribute to indicate that a menu item is busy. Like a disabled menu item, clicks will be suppressed until the loading state is removed.

<sl-menu style="max-width: 200px;">
  <sl-menu-item>Option 1</sl-menu-item>
  <sl-menu-item loading>Option 2</sl-menu-item>
  <sl-menu-item>Option 3</sl-menu-item>
</sl-menu>

{% raw %}

import SlMenu from '@onsonr/nebula/dist/react/menu';
import SlMenuItem from '@onsonr/nebula/dist/react/menu-item';

const App = () => (
  <SlMenu style={{ maxWidth: '200px' }}>
    <SlMenuItem>Option 1</SlMenuItem>
    <SlMenuItem loading>Option 2</SlMenuItem>
    <SlMenuItem>Option 3</SlMenuItem>
  </SlMenu>
);

{% endraw %}

Checkbox Menu Items

Set the type attribute to checkbox to create a menu item that will toggle on and off when selected. You can use the checked attribute to set the initial state.

Checkbox menu items are visually indistinguishable from regular menu items. Their ability to be toggled is primarily inferred from context, much like you'd find in the menu of a native app.

<sl-menu style="max-width: 200px;">
  <sl-menu-item type="checkbox">Autosave</sl-menu-item>
  <sl-menu-item type="checkbox" checked>Check Spelling</sl-menu-item>
  <sl-menu-item type="checkbox">Word Wrap</sl-menu-item>
</sl-menu>

{% raw %}

import SlMenu from '@onsonr/nebula/dist/react/menu';
import SlMenuItem from '@onsonr/nebula/dist/react/menu-item';

const App = () => (
  <SlMenu style={{ maxWidth: '200px' }}>
    <SlMenuItem type="checkbox">Autosave</SlMenuItem>
    <SlMenuItem type="checkbox" checked>
      Check Spelling
    </SlMenuItem>
    <SlMenuItem type="checkbox">Word Wrap</SlMenuItem>
  </SlMenu>
);

{% endraw %}

Value & Selection

The value attribute can be used to assign a hidden value, such as a unique identifier, to a menu item. When an item is selected, the sl-select event will be emitted and a reference to the item will be available at event.detail.item. You can use this reference to access the selected item's value, its checked state, and more.

<sl-menu class="menu-value" style="max-width: 200px;">
  <sl-menu-item value="opt-1">Option 1</sl-menu-item>
  <sl-menu-item value="opt-2">Option 2</sl-menu-item>
  <sl-menu-item value="opt-3">Option 3</sl-menu-item>
  <sl-divider></sl-divider>
  <sl-menu-item type="checkbox" value="opt-4">Checkbox 4</sl-menu-item>
  <sl-menu-item type="checkbox" value="opt-5">Checkbox 5</sl-menu-item>
  <sl-menu-item type="checkbox" value="opt-6">Checkbox 6</sl-menu-item>
</sl-menu>

<script>
  const menu = document.querySelector('.menu-value');

  menu.addEventListener('sl-select', event => {
    const item = event.detail.item;

    // Log value
    if (item.type === 'checkbox') {
      console.log(`Selected value: ${item.value} (${item.checked ? 'checked' : 'unchecked'})`);
    } else {
      console.log(`Selected value: ${item.value}`);
    }
  });
</script>

{% raw %}

import SlMenu from '@onsonr/nebula/dist/react/menu';
import SlMenuItem from '@onsonr/nebula/dist/react/menu-item';

const App = () => {
  function handleSelect(event) {
    const item = event.detail.item;

    // Toggle checked state
    item.checked = !item.checked;

    // Log value
    console.log(`Selected value: ${item.value}`);
  }

  return (
    <SlMenu style={{ maxWidth: '200px' }} onSlSelect={handleSelect}>
      <SlMenuItem value="opt-1">Option 1</SlMenuItem>
      <SlMenuItem value="opt-2">Option 2</SlMenuItem>
      <SlMenuItem value="opt-3">Option 3</SlMenuItem>
    </SlMenu>
  );
};
