| 19 `<iron-dropdown>` is a generalized element that is useful when you have |
| 20 hidden content (`.dropdown-content`) that is revealed due to some change in |
| 21 state that should cause it to do so. |
| 22 |
| 23 Note that this is a low-level element intended to be used as part of other |
| 24 composite elements that cause dropdowns to be revealed. |
| 25 |
| 26 Examples of elements that might be implemented using an `iron-dropdown` |
| 27 include comboboxes, menubuttons, selects. The list goes on. |
| 28 |
| 29 The `<iron-dropdown>` element exposes attributes that allow the position |
| 30 of the `.dropdown-content` relative to the `.dropdown-trigger` to be |
| 31 configured. |
| 32 |
| 33 <iron-dropdown horizontal-align="right" vertical-align="top"> |
| 34 <div class="dropdown-content">Hello!</div> |
| 35 </iron-dropdown> |
| 36 |
| 37 In the above example, the `<div>` with class `.dropdown-content` will be |
| 38 hidden until the dropdown element has `opened` set to true, or when the `open` |
| 39 method is called on the element. |
