Thanks,
Yes I looked into this option, but as far as I understand floating fields can only be related to data sources. They can not be filled in manually when filling in the form.
In our case often unique custom text needs to be entered in the text field, so using a floating field would not really work. If there is a way to make floating field so that it can simply be filled in, I would be very interested to know that. Although drop down choices could not be used then, it would still help me a step further.
