Cheers to you all: I am a beginner.
I want to create a search, possibly with Spinner (alternatively I'm also trying with LastPicker), articulated as follows:
. a list of items; and so far OK with both; the following, the darkness...;
. The choice that is made will be the key to obtaining a subsequent search list;
. The result of this search will also be the key to getting another list.
I ask you for help because I can't go on.
Thanks in advance
PS
I attach two images of what I wrote
You have to tie lists together in tables to link levels.
An example:
Thank you.
Tomorrow I will study the example and hope to move forward.
Tomorrow because in Rome (IT) it's time to go to bed. 
For now, thank you.
Anyway I'll keep you informed. 
Later I will deepen the study of the bellismo gift that you have highlighted to me.
But I realized that I was not precise in my request: my problem is in inserting, in the Spinner the list of choices through "blocks" and not from "design": if for the first Spinner I could use "ElementsFromString", for the subsequent ones that are different for each choice, how can I do?
Thank you
index of "Select Iist Item" should be a number, not a string.
Thanks,
I try and I refer you 
I am happy to inform you that I solved the problem of inserting in "ElementForString" of "Sinner" the list to be shown: I tried in many different ways and in the end this gave me the desired result.
How big is this going to grow, that you have to code blocks for every choice?
You're absolutely right: but that's how it works. If you have any suggestions to lighten, please, let me know
