How to Allow Authors to Select Multiple Submission Topics in Dryfta

In Dryfta's Advanced Setup for abstract submissions, is there a way to make the Submission Topics field a 'select all that apply' option so that authors can select all relevant topics for their submission?

In Dryfta, the standard 'Submission Topics' field allows authors to select a primary topic only. To enable authors to select multiple topics relevant to their submission, you can use two separate fields under 'Submission Questions':

1. Use the 'Submission Topics' field to allow authors to select the primary topic.
2. Use the 'Sub Topics' field to let authors select additional relevant topics.

Within the 'Sub Topics' field settings, select the option 'Primary topic' for 'Display additional topics as sub-topic or primary topic?'. This setup lets authors select multiple topics while maintaining a clear primary topic.
