You should use radio groups instead of checkboxes. The radio group allows you to just select one inside a set of radio buttons. What do you want to do with the list of checkboxes?

Hi andrew mahfouz,

As you mentioned list of checkbox, it must be the aggregate source or local variable of list datatype

For aggregate,

Step1 : Create a calculate attribute in aggregate

Step2 : Bind the current calculated attribute to the checkbox

For local variable of list datatype,

Step1 : create a attribute in the structure of boolean datatype

Step 2: Bind the current  attribute to the checkbox

Hope this helps!

Hi Andrew,

As Marcio said its better to use radio button group.

But if its mandatory to use checkbox you can you will need to make use of On Change event of checkbox  if you bind list of Boolean to checkboxes when select one to loop this list and check other checkboxes variable to false

Hi Andrew,

I did a workaround for your scenario, to handle Checkboxes act like radio buttons in a list. Please find the OML and URL for your reference.
