Hello

In the hikashop product listings, I have set a filter by price range, but I want to improve its functionality and I have two queries.
1- I need to know if it is possible to dynamically configure the range caps, according to the price of the lowest and highest priced product, the lower range is not so important, but the upper range is very important, because in the current way , the site administrator should be checking daily if a product has been published with a price higher than the configured range.

2- The price range filter uses a cursor to modify the range, the problem is that when moving the cursor, next to the button to clean the filter, a colon symbol ":" is displayed, inspecting the html code, the symbol It not seem to be included in an html tag, when cleaning the filter, the symbol disappears. How could I remove the symbol? What is the filter view? where to check if it is something that was wrongly encoded.

Hello, thanks for the answer

1- Can you tell me how to configure the price range filter, so that the upper limit takes the price of the product with the highest value in the list?

2- effectively, changing the translation override, the colon symbol is no longer displayed.

Thanks greetings !

Hi, thanks for your response

It is correct, my apologies, I think that because of the translation I could not understand your answer.

Thanks greetings !
