How can I add filter textbox in Hydrogen for data retrieval?

Hello everyone,

I would like to add several textbox type filters in order to retrieve the data to perform a calculation and filter according to the result of my calculation.

I don’t think I can do this natively with shopify. So I tried using Hydrogen. But I have some concerns.

1st try:

  1. I installed the latest version of Hydrogen via my terminal
  2. I linked my project with my native store
  3. My project has been added to my github

2nd try

  1. I created my project from the Hydrogen channel
  2. I followed the git commands for pull and linked my project to the native store
  3. My project has been added to my github

Problems :

  1. My theme is completely broken. I don’t know how to get my theme from my native store. Or I didn’t understand the concept well and I have to make my own design. But it would be a bit stupid to lose the themes offered by Shopify
  2. I cannot retrieve the new products added to my native store

I must have missed something. Could you help me ?

THANKS
