);

Disabled

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

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

import { MOMenu, MOMenuItem } from '@metsooutotec/modes-web-components/dist/react';

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

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.

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

import MOMenu from '@metsooutotec/modes-web-components/dist/react/menu';
import MOMenuItem from '@metsooutotec/modes-web-components/dist/react/menu-item';

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

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 mo-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 type=“checkbox” checked state, and more.

Option 1 Option 2 Option 3 
<mo-menu class="menu-value" style="max-width: 200px;">
  <mo-menu-item type="checkbox" value="opt-1">Option 1</mo-menu-item>
  <mo-menu-item type="checkbox" value="opt-2">Option 2</mo-menu-item>
  <mo-menu-item type="checkbox" value="opt-3">Option 3</mo-menu-item>
</mo-menu>

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

  menu.addEventListener('mo-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>

import { MOMenu, MOMenuItem } from '@metsooutotec/modes-web-components/dist/react';

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

    // Toggle type="checkbox" checked state
    item.checked = !item.checked;

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

  return (
    <MOMenu style={{ maxWidth: '200px' }} onMoSelect={handleSelect}>
      <MOMenuItem type="checkbox" value="opt-1">Option 1</MOMenuItem>
      <MOMenuItem type="checkbox" value="opt-2">Option 2</MOMenuItem>
      <MOMenuItem type="checkbox" value="opt-3">Option 3</MOMenuItem>
    </MOMenu>
  );
};
