Currently the multi select field works as follows:
Let's say a multi select has the following options
- Option A
- Option B
On the first submission, if the contact selected
- Option A only then, the property will have a value of A
On the second submission, if the contact selected
- Option B only then, the property will update (and overwriter previous submission) to have a value of B only
On the third submission, if the contact selected
- Options A and B, then the property will update (and overwrite previous value of B) to have both value A and B
So the field always reflects the most recent value chosen. However it'd be very useful if this could be accumulative. That is, if the contact was interested in Option A originally, and now is interested in Option B - the property shows that they are interested in both Option A and Option B.
This is possible when manually editing the field, however not possible when the field is updated via form as far as I can see.
