My forums contain categories which are used by gaming guilds as their clan forums. I would like to offer each guild the opportunity to customize their category a bit. Specifically I would like to provide them the ability to use their own background image and sidebar blocks. I found the background image code within template xenforo.css. What is the best way to set up a conditional to change the image based on the forum node? And do I need to list each forum node? or can I just list the category and then all child nodes are covered? I also desire to add sidebar blocks for things like their ventrilo server and such but only within their guild category. I understand the background css is contained within xenforo.css and the sidebar control is contained within forum_list templates. Basically I need to understand how to write a conditional for nodes and apply it in these two circumstances. I did review the FAQ for conditionals and didn't see anything directly relevant. The closest I saw was conditionals based on user groups which would not be ideal in this situation.
