How does Extension:CategoryTree work? I can't get the arrows to show up on my Wikia wiki. Can someone give me a working example on Wikia?
 * https://www.mediawiki.org/wiki/Extension:CategoryTree
 * https://www.mediawiki.org/wiki/Extension:CategoryTree

The top category here at the Community Central wiki is:
 * Category:Browse

Its classic category tree is created here by choosing "pages except files" from the dropdown menu:
 * Special:CategoryTree

The classic category tree starting at the Browse category is this:
 * https://community.wikia.com/index.php?title=Special%3ACategoryTree&target=Browse&mode=pages&dotree=Show+tree

Can this be set up to be opened by default without clicking it?
