Please find the attached file. replace the refresh with rebuild. $('#cmbCity').multiselect('rebuild') i have updated the code and add some css file for better ui.

You should take cityid array and everytime multiple cityid coming from database should assign to listbox... public class Model { public int ? StateID { get ; set ; } public string [] CityID { get ; set ; } }
