Bootstrap scrollspy MDB Pro component

Bootstrap scrollspy is a plugin which shows on the navigation list current position on the page depends on the scroll position defined by the user.


How it works

Bootstrap scrollspy is a plugin which shows on the navigation list current position on the page depends on the scroll position defined by the user.

  • If you’re building our JavaScript from source, it requires util.js.
  • It must be used on a nav component or a list group.
  • Scrollspy requires position: relative on the element you’re spying on, usually the <body>.
  • When spying on elements other than the <body>, be sure to have a height set and overflow-y: scroll applied.
  • Anchors ( <a>) are required and must point to an element with that id.

When successfully implemented, your nav or list group will update accordingly, moving the .active class from one item to the next based on their associated targets.

Usage

Via data attributes

To easily add scrollspy behavior to your topbar navigation, add data-spy="scroll" to the element you want to spy on (most typically this would be the <body>). Then add the data-target attribute with the ID or class of the parent element of any Bootstrap .nav component.

                
body {
  position: relative;
}
                
                

<body data-spy="scroll" data-target="#navbar-example">
  ...
  <div id="navbar-example">
    <ul class="nav nav-tabs" role="tablist">
      ...
    </ul>
  </div>
  ...
</body>

Via JavaScript

After adding position: relative; in your CSS, call the scrollspy via JavaScript:


$('body').scrollspy({ target: '#navbar-example' })

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>.

Non- :visible target elements ignored

Target elements that are not :visible according to jQuery will be ignored and their corresponding nav items will never be highlighted.
