[Qgis-user] QGIS form with multiple cascading elements

[Lene Fischer]

Hi Felix,
I have this video in Danish… https://youtu.be/8shIZrwlQt4?t=975
There are 2 lookup tables and I use the value as you mention – try to look – not listen ;-)

Subject: [Qgis-user] QGIS form with multiple cascading elements

Hallo,
i want to build a custom QGIS form with multiple cascading elements.
They all should refer to the direct previous selection and only the first element is hardcoded vis "value mapping" (not sure if the right english term, "Wertabbildung" in german...).
I refer to the previous selection via: "..."=current_value('...') and have imported multiple csv tables with my pairs of values.
My problem is, that only the first cascading element works (that refers to the hardcoded values), all following once dont allow any selection, or they show all values that are present in the relating csv table.

Doesnt the cascading form works with multiple elements or where could i improve? I also tested a very very simple relation table, to eliminate misspelling etc. but that one also behaved like the other tables.

Thank you and greetings,
Felix
