Currently the option allows you to select only one time or duration option from a drop down menu at the top of the form, but that doesn't always work if a volunteer is entering multiple entries. For example, it would be great to be able to submit a list of donated items without needing a time entry, then submit the hours for a planning meeting, & also submit volunteer hours for a field trip. The second additional questions would be configured to appear after one of the ways to volunteer was selected (marked as a YES). It would look something like this:

Administrative Meeting: (they mark YES)
Then two new boxes pop up:
One that asks what kind of meeting: (they select one ie: Health)
Another that asks How long was your meeting: (ie: 2hrs)

Did you make a donation?: (they mark yes)
Then several other boxes pop up, such as:
List your donation items: (they enter everything in)
What was the total/est. cost of the items donated?: (ie: $50)
Please attach a pic of your receipts: (they upload pic)

Did you volunteer as a chaperone?: (they mark YES)
Then more fields appear, such as:
Teacher's Name: (they select from a list: Mr. Bell)
Time In: (ie: 10am)
Time Out: (ie: 3pm)

The idea is for volunteers to be able to enter multiple entries on the one form rather than having to submit 4-5 entries consecutively.
