Hide Select All from Dropdown list

I have a dropdown list which allows multiple values. However, the dropdown shows a 'Select All' choice. How can I hide this as it is shown at the top and 'Select All' makes no sense for my choices. Ideally this ought to be a property for dropdown lists for the column
