I am trying to create a page that show a list of products that have price which is greater than some specific amount and i also want to add Layered navigation for filter these product collection based upon different attribute. But in Magento 2.4.1 when i implement the code for layered navigation in layout file it not properly work and show a layered navigation.
So Here the specific attribute product list are correctly show on custom page, but when i add layered navigation functionality the custom page are not properly render and Layered navigation not work properly.
And When i click on Above page generated link it show product page data like this:-
And if we click on any generate data link it redirected to custom product page with already layered navigation applied but not properly worked.
