Hi,
Let's say I sell sporting goods.
I would like to have a few sideboxes menus by attributes.
For example one by sports (baseball, hockey, etc).
Another one by type (clothing, balls, shoes)
Another one by age (children, adults, etc)..

You get my point

How could I do something like this?
Is there a module? or what files can be used as reference?
Any pointers?

Thanks.
