I'm just trying to do a simple radio button for test purposes. So I got the codes from W3School here
I manage to create the
Radio Button. However, after I press
save and try out the
radio button, I found out that I am able to check both the buttons. It's supposed to check only one, and not more than that. However, somehow I manage to check more than one.
I found out that some of the code I added earlier on have been deleted. The name attribute in the code have been deleted, and that's why I am able to check two.
How can I stop SharePoint from deleting it?
