According to the option selected I want some panels to be hidden . Eg:- If there are 3 options in dropdown :- 1.) Layout1 , 2.)Layout2 , and 3.) Layout3
And if user selects Layout1 then out of 6 panels 4 should be visible . If user selects Layout 2 then all 6 panels should be visible and if user selects Layout 3 then only 2 panels should be visible .
How should I achieve this?
