Create an action rule to do that :-
Add an action rule on control on onChange event:
For specific control (change the control id)
$('#AdvancedLookup1').parent().find('.token').css('white-space','normal').css('height','auto')
Or
For general token in page
$('.token').css('white-space','normal').css('height','auto')
In general, this should be fixed by the control design, the width and height of the control should take the included data into consideration.
Note : if the data inside the control is large, the control will not push down other controls and will get over them.
