FreeMarker loop over items

<#-- 1. Define an array (sequence) of objects (hashes) -->
<#assign links = [
  { "label": "Home",     "url": "/",           "active": true },
  { "label": "About",    "url": "/about",      "active": false },
  { "label": "Contact",  "url": "/contact",    "active": false }
] />

<#-- 2. Iterate and render HTML -->
<ul class="nav">
  <#list links as link>
    <li>
      <a href="${link.url}">${link.label}</a>
    </li>
  </#list>
</ul>
