Currently I am using twenty ten theme which came as a default with wordpress.
In the categories section, in order to dispaly sub catergoies, I can see the heirarchical structure and have them in drop down box.
My requirement is to have a list of categories and sub-category with expand-contract feature using plus and - sign.
On click of plus (+), the sub categories will be seen
On click of minus (-), the sub-categories will be hidden
Currently, the same kinda feature is there in project explorer in eclipse.
Please guide me for the same.
