Material design: [Lists](https://www.google.com/design/spec/components/lists.html)
|
|
|
|
`<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>
|
|
|
|

### Accessibility
