Dear Andrei, i was looking for some tips for creating the list of elements out of the array returned from the MySQL query, but havn't found any. The only solution here is a setting already predefined list (array) of strings, to push it to the dropdown list. Could you please suggest how i can access …

can you share an example of what the existing array looks like and which parts need to be in the dropdown ?

Hi, I dont have a MySQL to play with so I have simulated data with an inject node & fully commented a function node to help you. The heart of this solution is to transform whatever format you get from the database (use a debug node to determine that) into a format the dropdown node likes (see the i…

Hi Liudmila, welcome to the forum. I am late to the party as Steve already provided a nice working example. If you share with us how the returned MySQL query looks like and how the dropdown should be then we could see how the solution from Steve could be adapted to fit your use case.

Since the structure of your data matches the structure of the dropdowns required msg.options you're getting exactly what you give it. What is it you want displayed in the dropdown & what do you want for the value when its selected? According to your screen shot you have "part_number_item" or its "…

See my second response above ^ :slight_smile:

Can i ask you one more question thought, everything is working, but the first time it gave me such an ugly screen: [immagine] when i choose one of the value everything is gone, but the first time i get all the returned values on the screen. What's wrong with my flow?
