I've got an HTML div composed of many rows (using angular so the number of rows is dynamic). Inside these rows are columns or <td> tags. Inside some of these <td>'s are forms with radio buttons. If a radio button in one form is clicked, I need all the other radio buttons in the same column (but different rows and therefore, different forms) to become unchecked. Normally, if the radio buttons all belong to the same group, this functionality is built in. I'm trying to link radio buttons across form elements. Is this possible? How?
