Block category modification

[arjundass]

I have modified the block category module , such that when we click on any category , it display sub-categories , and after lick on sub-category , it takes us to sub - category page .

On this , sub-category page , I need , when you click on category , it should display all categories rather than showing and hiding the sub-categories. and also when you click on category , how can i hide automatically close the other catrgory which is displaying it,s sub-categories.

Any help would be much grateful.

Thanks.
