Allowing Only One Check Box to be Selected

To prevent a user from selecting more than one Check Box for the associated Custom Field, add this code to the HTML Tag section of the Custom Field:

onclick="onlyonechecked(this)"

This can be used for:

• Select Many - Check Box

and

• Select Many - Scrolling Check Box

The user will not be able to select more than a single check box with this code in place.

For the Select One - Combo Box, the "Show as Radio Buttons" option can be selected to display the field selections as "radio buttons."

Note

• If using onlyonechecked on a Select Many - Check Box field and you also want to Show/Hide Header you should use _showhideheader instead of _showhideheadercheckbox
