ScrollSpy 🔗

Update nav targets based on scroll position automatically.

Example 🔗

The navigation on the right is a live demo of the scrollspy directive (hidden on mobile devices).

Another example below, scroll the area below the navbar and watch the active class change. The dropdown sub items will be highlighted as well:

<template>
  <section>
    <nav class="navbar navbar-default navbar-static"  v-scrollspy:scrollspy-example>
      <div class="container-fluid">
        <div class="navbar-header">
          <button class="collapsed navbar-toggle" type="button" @click="show=!show">

            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
          </button>
          <a role="button" class="navbar-brand">Project Name</a>
        </div>
        <collapse class="navbar-collapse" v-model="show">

Usage 🔗

v-scrollspy:arg="option"

Where:

• arg is the ID (without prefix #) of the element to scrollspy on (optional), leave it empty to spy on <body>.
• options is an object of configuration (optional).

Bootstrap nav required 🔗

Scrollspy currently requires the use of a Bootstrap nav component for proper highlighting of active links.

Resolvable ID targets required 🔗

Navbar links must have resolvable id targets. For example, a <a href="#home">home</a> must correspond to something in the DOM like <div id="home"></div>.

Relative positioning required 🔗

No matter the implementation method, scrollspy requires the use of position: relative; on the element you're spying on. In most cases this is the <body>. When scrollspying on elements other than the <body>, be sure to have a height set and overflow-y: scroll; applied.
