Hi @Babloo
Here is how I was able to get this running in our Viya 3.5 now 😊
Created a new Job Definition called 'getDsColValues' with 'No embedded form', that accepts two custom parameters (s_dsName, s_colName) and returns a unique list of values in JSON format.
The Job was saved under the Public Folder (/Public/getDsColValues). Here is it's SAS code.
/* Generate unique list of values */
Proc summary data=&s_dsName NWAY missing;
class &s_colName;
output out=work._unique(drop=_type_);
run;
proc json out=_webout pretty nosastags;
export work._unique;
run;
Created Job Definition called 'DsDrivenLists', with HTML from, and saved it under the Public folder (/Public/DsDrivenLists). Here is the HTML form Code, which was inspired by this example sas-viya-programming/communities/SAS/JES_selectOutputFormat at master · sassoftware/sas-viya-programming · GitHub

<link rel="stylesheet" href="/SASJobExecution/theme">

The prompts below contains items pulled dynamically from SAS data sets.

To view data set records, make a seletion and press 'submit'

I stopped here once I was able to populate my HTML Select/DropDown widgets from SAS, after all, this is just Prove of Concept 😉
I hope this gets your closer to your goal.
But I'll just repeat my advice again, for SAS Viya 3.5 stick with the TASK Prompts, out of the box, they are probably a lot more feature rich compared to what you would spend time to build using JavaScript/HTML/CSS combination.
Good luck,
Ahmed
