In that case you should use ListBox control instead of dropdown and Set the SelectionMode property to Multiple

<asp:ListBox runat="server" SelectionMode="Multiple" >
  <asp:ListItem Text="test1"></asp:ListItem>
  <asp:ListItem Text="test2"></asp:ListItem>
  <asp:ListItem Text="test3"></asp:ListItem>
</asp:ListBox>

@Sachin How to make the listbox only shows the options on user click? The list box is showing all the options by default. can we avoid this – Beingnin Aug 28 '17 at 04:50
You can refer this Link [Add and display CheckBoxList (CheckBoxes) in DropDownList](https://www.aspsnippets.com/Articles/Add-and-display-CheckBoxList-CheckBoxes-in-DropDownList-in-ASPNet.aspx) for dropdowncheckboxlist using bootstrap and multiselect. – Ashi Feb 13 '20 at 09:19

Take a look at the ListBox control to allow multi-select.

<asp:ListBox runat="server" ID="lblMultiSelect" SelectionMode="multiple">
            <asp:ListItem Text="opt1" Value="opt1" />
            <asp:ListItem Text="opt2" Value="opt2" />
            <asp:ListItem Text="opt3" Value="opt3" />
</asp:ListBox>

in the code behind

foreach(ListItem listItem in lblMultiSelect.Items)
    {
       if (listItem.Selected)
       {
          var val = listItem.Value;
          var txt = listItem.Text; 
       }
    }

For multiple selection dropdown list,cannot accomplish it directly using dropdown..Can be done in similar ways..

Either you have to use checkbox list or listbox (ajax inclusive)

Dropdown list wont allows multiple item select in dropdown.

If you need , you can use listbox control..

ASP.NET List Box
