Hi Everyone, In advanced search section, after a category is selected, the extra fields that has been defined in the admin side will appear...So now under this example, 3 groups of check box under music category...Pop, Rock and Metal Each group will show different types of selections...originally, all 3 groups will show the same time... But now what I am trying to attempt is to show radio buttons first showing the group name first, so instead of showing all 3 groups of check box at one time, I try to filter by using radio button first...So only one selection can be made at one time.... I know how to show the radio button, but i am not sure how to continue from there...My idea is that if i click on radio button "Pop" or "Rock", it will automatically called out the action...Can this be done in this case... Thank you, Leo
