Roll call tags can be configured in either single or multiple tables. Before you configure roll call tags, you must configure a special tag that displays at the top of the tag template. This tag tells the system which table configuration to use.
If you want to use a single table configuration, the tag would be:
<roll_call_options singletable="true">
If you want to use the multiple table configuration, the tag would be:
<roll_call_options singletable="false">
