Use WPF Extended Tookit. It may helps you
enter image description here

Here is the link: WPF Toolkit CheckComboBox

Usage

 <xctk:CheckComboBox x:Name="_combo" 
                     HorizontalAlignment="Center" 
                     VerticalAlignment="Center" 
                     DisplayMemberPath="Color"
                     ValueMemberPath="Level"
                     SelectedValue="{Binding SelectedValue}"
                     SelectedItemsOverride="{Binding SelectedItems}" />

SelectedItems is read only, to get selected items IList.

 <xctk:CheckComboBox x:Name="_combo" 
                     HorizontalAlignment="Center" 
                     VerticalAlignment="Center" 
                     DisplayMemberPath="Color"
                     ValueMemberPath="Level"
                     SelectedValue="{Binding SelectedValue}"
                     SelectedItemsOverride="{Binding SelectedItems}"

...but its tricky. SelectedItemsOverride should be ObservableCollection with get; set; and base on ItemSource.
