All the widgets I'm listing below track user selection for each submission. This would mean that when someone picks a slot/date/item/etc it will be counted towards the submission and the widget counter will reduce by 1. Feel free to check them out and pick one that will suit your needs.

1. Inventory Widget

2. Gift Registry Widget

3. Ticket Purchases Widget

4. Appointment Slots Widget
