If you are having a dinner and want people to supply some of the items, create an event and send the link to those who have planned to bring items! They can choose which item they're bringing when they register.
If you don't want this signup to appear on your Signups page, choose Do not include, and send the link to those you want to bring dishes.
Create selections to use as the dishes people can sign up to bring.
Make sure you enter the maximum number of dishes by clicking Edit Capacities.
Add any questions in the Registration Questions tab to make sure the food gets where it belongs.
If you don't need to collect any extra information, consider making this event a simple signup!
Once the signup is created, send the link to those who will want to register to bring a dish. When they go to the link, they can click Register to choose what type of dish they want to bring.
The person will choose what type of dish they'll be bringing as their selection, answer any questions you've added, and receive a confirmation email once they've finished registering.
