In Nintex Form displayed Choice control as "Drop-Down Menu". There are many option choices in Drop-Down menu. It allows only one selection, however, as per the requirement multiple selection should be enabled. Is multiple selection possible in Choice control - Drop-down option?
Here I have to make clear that, in SharePoint a Choice type column has created with display choice as "Drop-Down Menu". I can not use other options like "Checkboxes" which allows multiple selection since there are many choice items in this column. Please find the screen shot of SharePoint column settings.
