How to see values from relational field?

[Apfelstrudel]

Hello,

I want to create a DB with some relational fields.

But how can the user see which entries are available for this relational field? Do I have to force the user the enter every letter of the alphabet to see the available entries?

Yes, currently it works only this way.

Thanks, but in most of the cases this behaviour is senseless.
