Note : When item get inserted it will not replace or overwrite the item which was before current position although it will shift the position of other items to get added at the desired position
In order to make combo box such that item inserted by user get added before the selected position in the drop down list we have to do the following –
1. Create a combo box
2. Make the combo box editable using setEditable method
3. Set insertion policy of combo box to insert at before the current
4. Create label
5. Retrieve the insertion policy and show it with the help of label
Below is the implementation
