Custom Feature

Hello to all, Good day, I am new to Wix/EditorX , I just want to know where I can see examples on how can I achieve a desired feature. Currently I am creating a website that needed a custom feature that is not in Wix yet which is the request for quote.

I have created a dynamic page for my custom products table, I want it to function as submit a request quote for the selected product of interest. Please see the image below for what I like to achieve.

Where can I see examples on how can I achieve this? Thanks in Advance.
