While creating a checkbox group, the module did, in fact, show an option for 'single selection,' but it was greyed out and could not be changed.  After saving the field, that option disappeared and no longer does it force a single selection.

 

Is there any way to fix this, insofar as adding a checkbox group with only one selection as an option?

John,

Hi. Yes the standard HTML/ASP.NET control for CheckBoxList does not have a property called 'SelectionMode' which the standard Listbox field does have. You would have to add maybe multiple checkbox's or as you suggested in another forum post the listbox field with a single selection. Other options would be Radio Buttons maybe since you can specify the number of items per row?
