I need to implement multiple drop downs with same value

   for example 

  

      DropDown1(values: 1,2,3,4,5)

      DropDown2(values: 1,2,3,4,5)

      DropDown3(values: 1,2,3,4,5)

      DropDown4(values: 1,2,3,4,5)

     When we select the value from first drop down the value is not available in the remaining drop downs.

 

     example: From DropDown1 (Selected Value: 3)

                   Need to remove 3 from remaining dropdowns.
