Is possible to make dynamic dropdown options multiple select?

I'm nesting options in a dynamic dropdown, but I need the user to be able to select multiple options within each "parent" option.  Is this possible?  In the example below, is there a way to allow users to select multiple time slots within each "job"?

A. Work Registration Desk

   1. 9:00am-10:00am

   2. 10:00am-11:00am

B. Work Prize Wheel

   1.  12noon - 1pm

   2.  1pm - 2pm

   3.  2pm - 3pm

Unfortunately, multi-selection is not available with the dynamic dropdown widget. You can use the basic drop down instead if you want to make it multiple selections.

We also have a widget for multiple selections, please check it here: https://widgets.jotform.com/widget/multiple_selection
