Modification of filters on the OpenCart site

Add the "Parameters (filters)" button to the search results and personal collections:

Example pages:
https://tutrade.ru/index.php?route=account/persona...
https://tutrade.ru/index.php?route=product/search&...

Website: http://tutrade.ru
CMS: Opencart

1. Location.
The button should be located at the top of the search results and personal collections pages, similar to the button on the category and subcategory pages. (See screenshot)

2. Default filters.
When you click on the "Options" button, a list of common filters should open:
-Availability
- Category (first show the most relevant categories, where there are the most products, show only the first 5, the rest are hidden under the "Show more (29)" button, when clicking on which we show all the categories, if you also manage to implement the search here, then its generally super)
-Price
-Producer

3. Filtering by category.
If the user selects a specific category, additional filters applicable to products from this category should be loaded. Examples of such filters include sizes, colors, characteristics, and other attributes specific to the selected category.

4. Filtering by several categories.
If the user selects two or more categories, the filters should be limited to the common parameters that are present in all selected categories.

5. Example of a filter how it should look and work (Type any word into the search and see "Filters"): https://www.komus.ru/

6. Remove categories that are shown in search results (see screenshot). We remove because the same categories are sewn inside the filter.

7. All this should work on both the desktop and mobile versions of the site
