I have found 2 different ways to have field trip choices (an example activity) on an event registration form. Either use price set items with $0 cost, or a profile custom data set with a multi-select box. Both ways allow you to get a list of participants by field trip. The profile method results in a search filter for field trips on the List Participants form. For the price set method you have to use the custom search on price sets for events, not as useful. I initially preferred to have check boxes for each field trip in the custom data designer, but CiviCRM has a strange custom data set design where option check boxes are not treated as true/false, plus they are displayed like radio buttons: all on one line. Of course if an activity has a non-zero price then you would use price sets. (I am using 'activity' in the non-CiviCRM sense).

That's not quite right: each checkbox is treated as true/false, but when the data is stored all the values are serialized and stored together. As far as the data is concerned it works exactly the same way as multiselect, only the representation on the form is different.

If you don't like all the checkboxes being on the same line you should modify the "options per line" setting for that field. You could set it to 1 to have 1 per line.

That's why I posted this, I need to get this cleared up thanks. I didn't know about options per line. I dropped the checkbox idea a while ago and went with multi-select. If my karma keeps dropping I will have to get a new username :+> I don't get paid for any of this, and it's wearing me out. I told the organization I would set this up for them.
