I am an IT Engineer, my field of work is limited to Network & Servers... but I always try to learn new things.. coding is totally different for me... that's why I purchased both Appgini and Appgini helper (one line of code is ok for me)

I have read and implemented react to lookup method from Appgini Helper website, but I want to try something else, I don't know if it is possible...
in the attached, I want to make each field appear once the user has selected one by one..
sorry for my English, I hope it is clear ,, thanks in advance..
