Ajax categories dropdown with list of products in PrestaShop

Good morning we bought a Prestashop module step by step - categories how can I do so that in prestashop it shows me the 1st categories 2nd the subcategories of the 1st and in 3rd option the product. Greetings

Hello,
As i understand you need something like this:
- first dropdown: show categories
- second dropdown: show subcategory from selected category in first dropdown
- third dropdown: show list of products from this category

if so, you need to create block:
- with "depth" param: 2
- with "include products" param set to "yes"

exactly as i show on the screenshot:



then it will work in that way:
