##<paper-item>

Material design: Lists

<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:

    Show your status
  </paper-item-body>

</paper-item>

##<paper-icon-item>
