The subnavigation on the left is a live demo of the affix plugin.


Via data attributes

To easily add affix behavior to any element, just add data-spy="affix" to the element you want to spy on. Then use offsets to define when to toggle the pinning of an element on and off.

<div data-spy="affix" data-offset-top="200">...</div>
Heads up! You must manage the position of a pinned element and the behavior of its immediate parent. Position is controlled by affix, affix-top, and affix-bottom. Remember to check for a potentially collapsed parent when the affix kicks in as it's removing content from the normal flow of the page.

Via JavaScript

Call the affix plugin via JavaScript:



Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-offset-top="200".

Name type default description
offset number | function | object 10 Pixels to offset from screen when calculating position of scroll. If a single number is provided, the offset will be applied in both top and left directions. To listen for a single direction, or multiple unique offsets, just provide an object offset: { x: 10 }. Use a function when you need to dynamically provide an offset (useful for some responsive designs).
