Listing and filtering Json

hello, I am trying to make a page listing all the products and sort them on the fly by a filter, (json).
This filter contains a category_id, it is not a “select” but a simple listing of all products in the category.
Could you tell me the way to do that, I search in the forum, I have not found the solution.

Hi @clvdh,
Where is your data coming from? Is it a database, external API or a JSONfile on your server?
