How to group multiple check boxes?

[Shekharmine]

in above picture there are 5 categories.

i want each category as a separate group.

user can check all boxes in category. but he can choose any 1 category only.

if he select category 1 then he can check all 3 check boxes from that category.

if he checked category 2.. then category 1 will be unselected or unchecked.

As the MouseUp event of the "category 1" fields, for example, you can enter this code:

if (event.target.value!="Off") this.resetForm(["category 2", "category 3"]);
