I have a lot of brands.
I imagine customers will be selecting multiple brands from the filter list on collections page when they are browsing.
However, when you select a brand from the list, the page resets/scrolls back up to the top.
I have seen a few themes where this does not happen, and the URL is changed without refreshing.
Can you make this possible with your theme? So that customers can select multiple filters from the list and don't have to navigate back to their position?
