  <p>The <code class="language-markup">&lt;tc:treeCommand/></code> tag can be added to a
    <code class="language-markup">&lt;tc:treeNode/></code> tag.
    The command can be used to execute an action or a link.</p>

  <tc:section label="Example">
    <p>In this example, the nodes with children are displayed as
      <code class="language-markup">&lt;tc:treeLabel/></code>. The leafs are
      <code class="language-markup">&lt;tc:treeCommand/></code>.
      Like the parent nodes suggest,
      the entries in 'Actions' run an action with the <code>action</code> attribute.
      And the entries in 'Links' are links to an external website using the <code>link</code> attribute.</p>
