xF2 Add-on [XFI] Categories - collapse & expand 2.1.0

The [XFI] Categories - collapse & expand plugin will allow your users to enable the ability to collapse / expand categories.




Also there is the possibility to exclude certain categories for folding.
But, this is done in the style settings, where in order to exclude the necessary categories, you just need to specify their IDs separated by commas.




There are also group rights that allow you to disable this feature to a specific group.
