MultiChoice fixed height

Hi,

Is it possible to fix the height of the multi choice box. Once the user selects more values it gets bigger and goes behind the button. I tried the parameter max_height but did not work.

multi_choice = MultiChoice(height = 150, width = 300, max_height = 170, 
                           title = 'Search & Select Well:')
