Map Category List hidden by default? #2

I found that the following code worked but it deleted all the categories.
#geodir_map_v3_home_map_1_cat{display: none;}

What I want to do is to minimize the list as below.

<AS IS>
1. Restaurant
– Chinese
– Korean
2. Shop
– Supermarket
– Department store

<TO BE>*Click [+] to open children categories .
1. Restaurant [+]
2. Shop [+]

How can I make it happen?

Guust,

Thank you so much! I didn’t notice this. It worked!
