As you can see that What I want is when I change value in any of three then values in all should be affect.Now whats happening then values select in other two “empDepartment” and “empSubDept” are change but reverse is not working mean If I change values in “empCategory” then value in the “empSubDept” should also change
When the category event handler changes the content of the department select box, you just need that category event handler to also trigger the department event handler.
