i want hide description on test category and all sub category on list page.
It's a bit clunky but you can do this fairly easily using css.
In the front-end html you should have a categorypath-x class on the body element which you can target with attribute selectors to display:none the description for only the parent category and its children.
If this interests you but you don't know how to go about it I can post an example.
