# Milk: Collapsible panels

Collapsible panels allow your users to hide sections they view infrequently. Preferences are stored using HTML5 local storage, and therefore will be remembered between sessions. 

If enabled, collapsible panels will be available for the following containers:

* Categories
* Index page "Information" panel
* Viewforum "Information" panel
* Viewtopic "Information" panel
* Some sidebar panels if the example code has been used
