<paper-menu-button>

Material design: Dropdown buttons

paper-menu-button allows one to compose a designated "trigger" element with another element that represents "content", to create a dropdown menu that displays the "content" when the "trigger" is clicked.

The child element assigned to the dropdown-trigger slot will be used as the "trigger" element. The child element assigned to the dropdown-content slot will be used as the "content" element.

The paper-menu-button is sensitive to its content's iron-select events. If the "content" element triggers an iron-select event, the paper-menu-button will close automatically.

Example:

<paper-menu-button>
  <paper-icon-button icon="menu" slot="dropdown-trigger"></paper-icon-button>
  <paper-listbox slot="dropdown-content">
    <paper-item>Share</paper-item>
    <paper-item>Settings</paper-item>
    <paper-item>Help</paper-item>
  </paper-listbox>
</paper-menu-button>

Changes in 2.0

• neon-animation 2.0 doesn't import the Web Animations polyfill, so you'll have to import it (see example)

• Distribution is now done with the slot="dropdown-trigger" and slot="dropdown-content" attributes (replacing the classes of the same names)
