In this article, I will show you, how to add checkBoxList in DropDownList as item. I mean to say when you drop it then display item in the form of CheckBox list. You can select multiple items from CheckBox list. Selected Items show in the DropDownList header. If you want to design this types of DropDownList then add these files into your head section of page. By using these files, we can convert our ListBox into DropDownList with CheckBox Item. I will Give you complete example of Bootstrap Dropdown Menu.
