In this article we will see how we can add separator at the desired index in the combo box. By default there is no separator. Separator is the black line in between two items, in order to add the separator we use insertSeparator method. Below is representation of combo box items with a separator looks like – 
Syntax : combo_box.insertSeparator(index) Argument : It takes integer as argument i.e index Action performed : It will add separator at the given index
Note: If the index is equal to or higher than the total number of items, the new item is appended to the list of existing items. If the index is zero or negative, the new item is prepended to the list of existing items. Below is the implementation –
