Log in or register, to view the original You need to add sorting on the "Catalogue" page.The page contains a list of categories and a list of products, they are created from the JSON file through the "fetch" method.Logic is that: we click on the site's hat on "Catalog" or another category, we go to the "satalog.html" page and take the data from the data-atribut link we click on and add to the "session storage".When we go to the "satalog.html" page, the key and the value are taken from the "session storage", filtered from the JSON file and displayed on the page.This principle works with categories on the page.Now the principle of filters is that - when we enter and all the goods are displayed, then the filters are displayed all that is on the page, if we change the category, then the filters are displayed only those that are in this category on the product.More detailed, what to do - when we select the checkbox, only those goods in which the characteristics have this value are displayed.And you should cut the status of the checkbox after re-loading the page or when you went to the other and returned.Here is a link to GitHub with the main JS file and JSON - https://github.com/TryingCodin/Top-bud/blob/main/catalog-script.js The logic is a bit frozen, you can call, talk and explain everything.Please add the filter today.
