Hi every one ,

I actually need some suggestions or tutorial for organic groups development...

I want to show "Categories" When user clicks on this category it will show the "Subcategory" only related to that category , and if user clicks on any subcategory it will show all the related topics and when clicked on any topics it will show all the nodes on this topics , can be multiple ...

Hierarchy==== Category ---> subcategory ---> Topics --- > Nodes

is it posible using Organic groups ... if yes than please give me tips.. how can i do this...Or i have to use some thing else...?

Thanks
