How to create multiple select @html.dropdownlistfor in mvc

Sachin Singh · Answer

Use @Html.ListBoxFor() insted of @Html.dropdownlistfor() if you use @Html.dropdownlistfor() then use HtmlAttributes and define the multiple property. @Html.DropDownListFor(m => m.anyProp, Model.AnyList, new { @multiple = "multiple" }).

Please use ListBox for mulitple select in dropdown box. @Html.ListBoxFor( m => m.location_code, Model.location_type ) Hope it helps.

Use a ListBoxFor instead of DropDownListFor: @Html.ListBoxFor(m => m.name, Method.getName("", Model.name), "--Select--") @Html.ListBoxFor(m => m.department,Method.getDepartment(Model.name, Model.department), "--Select--") The name and department properties must obviously be collections that will contain the selected values. The HTML helper will automatically preselect the items whose values match those of the Name/Department property.
