Is it possible to extract table columns for values in data forms

I have a table with four columns and I want to use three (or two) of the columns as values in a data form with type select+multi+values. In a test topic I made an EXTRACT example that works but when inserting that into the values column of the data form definition the rendered form doesn't work. It seem to list all text in the referenced table topic (including META). Anyways it feels as this should be possible without too much hassle and preferably with DBCache data. Is there a way?

FilterPlugin's EXTRACT should handle that nicely. If you could please show us how you tried to implement it, we can proofread/troubleshoot it for you.

The problem was unexpected characters in the text, so rendering got screwed.

A little update. The problem was commas within the text used to display in the select box. That screwes up the format which is to be "Readable choice=$savedvalue". Here "Readable choice" actually was $formfield(Name) and $savedvalue would be the topic name because it is SomethingAUTOINC (like an index). The separator for data type select+values is comma, so when the "Readable choice" contains comma....blah. After knocking around I got it right with FilterPlugin, it just substitutes comma with nothing:

%<nop>DBQUERY{ "MyForm" separator=", " sort="Id" format="$formfield(Id) $percntSUBST{ text=\"$formfield(Name)\" pattern=\",\" }$percnt=$topic" }%
