Usage

Installation

npm install --save @polymer/iron-menu-behavior

In a Polymer 3 element

import {PolymerElement} from '@polymer/polymer/polymer-element.js';
import {mixinBehaviors} from '@polymer/polymer/lib/legacy/class.js';
import {html} from '@polymer/polymer/lib/utils/html-tag.js';

import {IronMenuBehavior} from '@polymer/iron-menu-behavior/iron-menu-behavior.js';

class SimpleMenu extends mixinBehaviors(IronMenuBehavior, PolymerElement) {
  static get template() {
    return html`
      <style>
        :host > ::slotted(*) {
          display: block;
        }

        :host > ::slotted(.iron-selected) {
          color: white;
          background-color: var(--google-blue-500);
        }
      </style>

      <slot></slot>
    `;
  }
}

customElements.define('simple-menu', SimpleMenu);

Then, in your HTML:

<script type="module" src="./simple-menu.js"></script>

<style>
simple-menu .iron-selected {
  background-color: blue;
  color: white;
}
</style>

<simple-menu>
  <div role="menuitem">Item 0</div>
  <div role="menuitem">Item 1</div>
  <div role="menuitem" disabled aria-disabled="true">Item 2 (disabled)</div>
</simple-menu>
