Here Mudassar Ahmed Khan has explained with an example, how to implement Bootstrap style DropDownList in ASP.Net using the jQuery Bootstrap Multi-Select Plugin. The Bootstrap style DropDownList will have Multiple Select (MultiSelect) options i.e. user can select multiple items (options) with the help of CheckBoxes and hence instead of DropDownList, ListBox control will be used.
