<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>
