Hi Wolff,

Maybe you should check out this entry in the forum (_btw_: I received it looking for „depending drop down“):  
[https://discourse.nodered.org/t/problem-with-drop-down-menu/34003](https://discourse.nodered.org/t/problem-with-drop-down-menu/34003)

There you find an option with msg.options to send the possible options for the dropdown; meaning: as soon as one value is selected in the first drop down you can serve the possible options to the second one.

_Update: just saw, that you know the msg.options already. :-/ - Do you definitely need to use the csv or does it maybe make sense to have the values in a function? Are the values updated regularly?_

Cheers  
Ranki
