Usual is this: Xenforo Community Forums (main page categories)->Xenforo Questions and Support->Threads I need this kind of hierarchy: Forum main page (categories)->categories_xyz->forums->Threads or Forum main page (categories)->forums_xyz->forums->Threads like: Xenforo Community Forums (main page)->Xenforo Questions and Support->ABCCDEFG->Threads So you have a forum in a forum or a forum in a category. The tree has one more branch. But the problem is, this node is static. When you create somewhere a thread, these nodes dont sort themselves. They stay fixed. When you create threads, it is sorted by date. So when someone posts a message, the thread moves to the head. But yet the parent node stays fixed. The problem is, that I will have 200 parents. Nobody will go in a category where you have 200 more categories. You must now go into every 200 categories to find the newest messages. It is static, not sorting themselve. I thought the problem is solved, when I have forum in a forum, but still it stays static. What can I do? Did you understand my problem? Is there a possibility to create somewhere x child nodes but let their threads be shown in just one forum? Like all the threads in those x childs together in one forum?
