Lookup - filter on external field

[KroonOfficeSol]

On a datacard a lookup field is created when the origin is a list or relation. I would be great if there is an option to filter the displayed values (in the dropdown box) based on an external control or multiple external controls. Do this like this:

• Make this an extra field in the advanced section (like the defaultvalue field)
• include filter on relationships datafield (so relationship.kolomname = control.text)
• include all operators (&&, "", in, exactin, !)
