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.
 
20
 
 
21
    <paper-item>Item</paper-item>
 
22
 
 
23
Use this element with `<paper-item-body>` to make Material Design styled two-line and three-line
 
24
items.
 
25
 
 
26
    <paper-item>
 
27
      <paper-item-body two-line>
 
28
        <div>Show your status</div>
 
29
        <div secondary>Your status is visible to everyone</div>
 
30
      </paper-item-body>
 
31
      <iron-icon icon="warning"></iron-icon>
 
32
    </paper-item>
 
33
 
 
34
To use `paper-item` as a link, wrap it in an anchor tag. Since `paper-item` will
 
35
already receive focus, you may want to prevent the anchor tag from receiving
 
36
focus as well by setting its tabindex to -1.
 
37
 
 
38
    <a href="https://www.polymer-project.org/" tabindex="-1">
 
39
      <paper-item raised>Polymer Project</paper-item>
 
40
    </a>
 
41
 
 
42
If you are concerned about performance and want to use `paper-item` in a `paper-listbox`
 
43
with many items, you can just use a native `button` with the `paper-item` class
 
44
applied (provided you have correctly included the shared styles):
 
45
 
 
46
    <style is="custom-style" include="paper-item-shared-styles"></style>
 
47
 
 
48
    <paper-listbox>
 
49
      <button class="paper-item" role="option">Inbox</button>
 
50
      <button class="paper-item" role="option">Starred</button>
 
51
      <button class="paper-item" role="option">Sent mail</button>
 
52
    </paper-listbox>
 
53
