A scrollspy and affixed enhanced navigation to highlight page sections

Latest Stable Version License Total Downloads Monthly Downloads Daily Downloads

Extends Yii Menu widget. This widget offers a scrollspy and affixed enhanced navigation (upto 2-levels) to highlight sections and secondary sections in each page. The affix widget can be used to generate both the:

  • Sidebar Menu: Displays the scrollspy/affix navigation menu as a sidebar, and/or
  • Main Body: Displays the main body sections based on the section & subsection headings and content passed.

note: If you have the header section fixed to the top, you must add a CSS class kv-header to the header container. Similarly, for a fixed footer you must add the class kv-footer to your footer container. This will ensure a correct positioning of the affix widget on the page.

The parameters to pass are:

  • type The affix content type. Must be either menu or body. Defaults to menu
  • items: The affix content items as an array. Check the affix combined usage for a detailed example.

Note: This extension is a sub repo split of yii2-widgets. The split has been done since 08-Nov-2014 to allow developers to install this specific widget in isolation if needed. One can also use the extension the previous way with the whole suite of yii2-widgets.


The preferred way to install this extension is through composer. Check the composer.json for this extension's requirements and dependencies. Read this web tip /wiki on setting the minimum-stability settings for your application's composer.json.

$ php composer.phar require kartik-v/yii2-widget-affix "@dev"
