| |
| `<paper-item>` is an interactive list item. By default, it is a horizontal flexbox. |
| |
| <paper-item>Item</paper-item> |
| |
| Use this element with `<paper-item-body>` to make Material Design styled two-line and three-line |
| items. |
| |
| <paper-item> |
| <paper-item-body two-line> |
| <div>Show your status</div> |
| <div secondary>Your status is visible to everyone</div> |
| </paper-item-body> |
| <iron-icon icon="warning"></iron-icon> |
| </paper-item> |
| |
| To use `paper-item` as a link, wrap it in an anchor tag. Since `paper-item` will |
| already receive focus, you may want to prevent the anchor tag from receiving |
| focus as well by setting its tabindex to -1. |
| |
| <a href="https://www.polymer-project.org/" tabindex="-1"> |
| <paper-item raised>Polymer Project</paper-item> |
| </a> |
| |
| If you are concerned about performance and want to use `paper-item` in a `paper-listbox` |
| with many items, you can just use a native `button` with the `paper-item` class |
| applied (provided you have correctly included the shared styles): |
| |
| <style is="custom-style" include="paper-item-shared-styles"></style> |
| |
| <paper-listbox> |
| <button class="paper-item" role="option">Inbox</button> |
| <button class="paper-item" role="option">Starred</button> |
| <button class="paper-item" role="option">Sent mail</button> |
| </paper-listbox> |
| |
| ### Styling |
| |
| The following custom properties and mixins are available for styling: |
| |

| `--paper-item-selected-weight`| The font weight of a selected item | `bold` |
| `--paper-item-selected` | Mixin applied to selected paper-items | `{}` |

| ### Accessibility |
| |
| This element has `role="listitem"` by default. Depending on usage, it may be more appropriate to set |
| `role="menuitem"`, `role="menuitemcheckbox"` or `role="menuitemradio"`. |
| |
| <paper-item role="menuitemcheckbox"> |
| <paper-item-body> |
| Show your status |
| </paper-item-body> |
| <paper-checkbox></paper-checkbox> |
| </paper-item> |
