Category Functions

hi, anyone knows how to make following functions happen:

1) how to build a search block for a certain category and its sub-categories? as my site might be with lots of categories, and need search box to find the categories easily.

2)increase information boxes in categories.add page, when add a new category, to enter more infomation related such as GPS info, category code 1, category code 2, alternative names.

3)show a certain category and/or sub-categories in google map and other maps.

many thanks in advance. :-) want your talent people give some help on this.

There is no simple way to do it with just few lines of code. Hire someone to perform this modification for you
