Hello,
Welcome to the support forum! Thanks for writing in with your questions.
1. Events
The GDV1 Events addon can be used to create one CPT to be used for events with dates. (GDV2 allows multiple event CPTs).
2. Can I add headers to be used for the listings? ie End Date.
Yes, all events have a start and end date, if I understand you correctly.
3. Can I also add Categories in addition to the post tags so the notifications can be more specific?
Yes, categories and events can both be added to events to classify them.
When you say notifications, what do you mean, exactly? Email?
4. CSV import
I took a look at the CSV file. If you wan to import events into the events CPT created by the events addon, try this:
1. Enable events addon
2. Add any custom fields that you want at GD – Events Settings – Custom fields
3. Add an event listing
4. Go to GD – General Dummy Data – Insert 10 events
5. View an event to make sure it works/looks right.
6. Export events at GD – Import/Export – Select Events – Export
7. Download the CSV, merge your data into the CSV (use LibreOffice only)
8. Import the data
Let us know how it goes and write back with questions.
