How to set form recipient via dropdown

With the HeyForm it is possible to define the recipient of the form via the user. This allows for instance to select a contact person.

Some background information: the recipient of the form is defined in HeyForm via the hidden field “admin”. Up to three recipients can be determined, the other recipients are then the fields “admin1” and “admin2”.

In the source code it looks like this:

<input type="hidden" name="admin" value="fnR/V3pyfnlyZHJ+Y3I5Y3JkYw==">

If you now create a Dropbox field with the same name, you can control the recipient via the form. The field is called “admin”. This overwrites the previously hidden field. The selection is entered by labeling, separated from the value by “|”. In this case the e-mail address.

In the form, the recipient is now specified via the selection field.
