Conditional value list
I have 3 Category. Each category must have many sub-category . Example, I have Computers and Food Category , The Computers Category have 3 sub-categories which is server, mainframe and desktop.The Food category contains 2 sub-category which is apple and mango.
The question is how can I setup the conditional value list to show only related sub-category. Example, when I choose Computers, The sub-category drop-down list will show only server, mainframe and desktop. when I choose Food, The sub-category drop-down list will show apple and mango.
