There seems to be an impedence mismatch between how gravity forms populates checkboxes or multi selects and how salesforce expects them.
The problem is that, for checkboxes, for instance, gravity forms wants to put them in an aggregate container. Each of these containers can only point to one element on the feed list, when in fact, each *checkbox* should point to one element on the feed list.
I tried to work around this by converting the series of checkboxes we use to be a multi-select instead. But when submitting a multi-select, salesforce picks up the submitted value like "foo,bar,baz" as an item in the picklist, instead of adding those three elements separately.
What's the best way to handle selecting multiple items from a list? Am I just missing something here? Or is it not currently supported?
