I'm able to populate the information in the lookup control with multi-select choice in Nintex Forms 2010.
I need either option:
- Change label for Add and Remove buttons to Remove and Add respectively
OR
- Populate all the values in right side box instead of left side box when the form gets opened. i.e. When the form is open I want left side box blank and right side should have all the values to select
Below is the control's image:
