| 20 ##<paper-dropdown-menu> | |
| 21 | |
| 22 Material design: [Dropdown menus](https://www.google.com/design/spec/components/
buttons.html#buttons-dropdown-buttons) | |
| 23 | |
| 24 `paper-dropdown-menu` is similar to a native browser select element. | |
| 25 `paper-dropdown-menu` works with selectable content. The currently selected | |
| 26 item is displayed in the control. If no item is selected, the `label` is | |
| 27 displayed instead. | |
| 28 | |
| 29 The child element with the class `dropdown-content` will be used as the dropdown | |
| 30 menu. It could be a `paper-menu` or element that triggers `iron-select` when | |
| 31 selecting its children. | |
| 32 | |
| 33 Example: | |
| 34 | |
| 35 ```html | |
| 36 <paper-dropdown-menu label="Your favourite pastry"> | |
| 37 <paper-menu class="dropdown-content"> | |
| 38 <paper-item>Croissant</paper-item> | |
| 39 <paper-item>Donut</paper-item> | |
| 40 <paper-item>Financier</paper-item> | |
| 41 <paper-item>Madeleine</paper-item> | |
| 42 </paper-menu> | |
| 43 </paper-dropdown-menu> | |
| 44 ``` | |
| 45 | |
| 46 This example renders a dropdown menu with 4 options. | |
| 47 | |
| 48 Similarly to using `iron-select`, `iron-deselect` events will cause the | |
| 49 current selection of the `paper-dropdown-menu` to be cleared. | |
| 50 | |
| 51 ### Styling | |
| 52 | |
| 53 The following custom properties and mixins are also available for styling: | |
| 54 | |
| 55 | Custom property | Description | Default | | |
| 56 | --- | --- | --- | | |
| 57 | `--paper-dropdown-menu` | A mixin that is applied to the element host | `{}` | | |
| 58 | `--paper-dropdown-menu-disabled` | A mixin that is applied to the element host
when disabled | `{}` | | |
| 59 | `--paper-dropdown-menu-ripple` | A mixin that is applied to the internal rippl
e | `{}` | | |
| 60 | `--paper-dropdown-menu-button` | A mixin that is applied to the internal menu
button | `{}` | | |
| 61 | `--paper-dropdown-menu-input` | A mixin that is applied to the internal paper
input | `{}` | | |
| 62 | `--paper-dropdown-menu-icon` | A mixin that is applied to the internal icon |
`{}` | | |
| 63 | |
| 64 You can also use any of the `paper-input-container` and `paper-menu-button` | |
| 65 style mixins and custom properties to style the internal input and menu button | |
| 66 respectively. | |
