Hello dinakaran,

Generally speaking, you will need to remove the data item from the widget data source in order to remove it from the popup list. Based on the given information, I assume that the widgets are bound to one ObservableArray. If this is the case, then you will need to use 3 different instances as this will give you the ability to modify them separately and hence hide the corresponding items in the different dropdownlist widgets.
If you are experiencing any issues with accomplishing your goal I will ask you to prepare a simple Dojo example that demonstrates the problematic situation. Thus I will be able to review the implementation and advice you further.
