Jump to Nav



Magellan allows you to create navigation that tracks the active section of a page your user is in. Pair it with our Sticky plugin to create a fixed navigation element.


You can use Magellan with any navigation element, like our Menu or your own custom component. Just add the attribute data-magellan to the container, and links to specific sections of your page. Each section needs a unique ID.

<ul class="horizontal menu" data-magellan>
  <li><a href="#first">First Arrival</a></li>
  <li><a href="#second">Second Arrival</a></li>
  <li><a href="#third">Third Arrival</a></li>
<div class="sections">
  <section id="first" data-magellan-target="first">First Section</section>
  <section id="second" data-magellan-target="second">Second Section</section>
  <section id="third" data-magellan-target="third">Third Section</section>

You can use Magellan with our Sticky plugin to create a persistent navigation header or sidebar.

This first example is a simplified version of the table of contents on the right side of this page:

<div class="large-3 columns" data-sticky-container>
  <nav class="columns sticky" data-sticky data-anchor="exampleId" data-sticky-on="large">
    <ul class="vertical menu" data-magellan>
      <li><a href="#first">First Arrival</a></li>
      <li><a href="#second">Second Arrival</a></li>
      <li><a href="#third">Third Arrival</a></li>

This example is the menu bar floating at the top of the page.

<div data-sticky-container>
  <div class="sticky" id="example" data-sticky data-margin-top="0" style="width:100%;" data-margin-bottom="0" data-top-anchor="topAnchorExample" data-btm-anchor="bottomOfContentId:bottom">
    <nav data-magellan>
      <ul class="horizontal menu expanded">
      <li><a href="#first">First Arrival</a></li>
      <li><a href="#second">Second Arrival</a></li>
      <li><a href="#third">Third Arrival</a></li>

JavaScript Reference


The file foundation.magellan.js must be included in your JavaScript to use this plugin, along with foundation.core.js.

Plugin Options

Use these options to customize an instance of Magellan. Plugin options can be set as individual data attributes, one combined data-options attribute, or as an object passed to the plugin's constructor. Learn more about how JavaScript plugins are initialized.
