I'm trying to acheive a category sidebar that shows the children of the current category.
So for example if my cat structure is as follows
When I am in the arts category page I want only Music, Literature to display in the sidebar
And when I click on music then Jazz and rock will display.
I'm currently using wp_list_categories("title_li=&child_of=$cat")
But it lists the sub-sub-categories as well. IS there anyway I can disable that?
