[](https://travis-ci.org/PolymerElements/paper-menu-button) _[Demo and API Docs](https://elements.polymer-project.org/elements/paper-menu-button)_ ##<paper-menu-button> Material design: [Dropdown buttons](https://www.google.com/design/spec/components/buttons.html#buttons-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 with the class `dropdown-trigger` will be used as the "trigger" element. The child element with the class `dropdown-content` 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.
