Do you want the categories to behave like a tree? If so, check out
acts_as_tree.

The quick way is to have a look at acts_as_tree for the categories.  In 
brief, you give your categories table a parent_id and tell the model 
that it acts_as_tree, and everything should fall into place.  You''ll 
then need to figure out how you want to specify which category is the 
parent of a new one on creation.

okay its hard. its not as easy as i thought

does the acts as list has a scaffold code? or do i need to create my own 
"category page"?

some code really would be very helpful.

I haven''t tried it yet, but the Ajax scaffolding might be useful here, 
as might the Scaffolding Extensions...  Google is your friend.

hi alex

i appreciate you helping me out

the ajax scaffold is pretty nice http://ajaxscaffold.height1percent.com/

but alas, both stuff you mentioned, doesn''t incorporate acts_as_tree on
their codes.
