[](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. Example: ```html Share Settings Help ``` ### Styling The following custom properties and mixins are also available for styling: | Custom property | Description | Default | | --- | --- | --- | | `--paper-menu-button-dropdown-background` | Background color of the paper-menu-button dropdown | `--primary-background-color` | | `--paper-menu-button` | Mixin applied to the paper-menu-button | `{}` | | `--paper-menu-button-disabled` | Mixin applied to the paper-menu-button when disabled | `{}` | | `--paper-menu-button-dropdown` | Mixin applied to the paper-menu-button dropdown | `{}` | | `--paper-menu-button-content` | Mixin applied to the paper-menu-button content | `{}` |
