Is it possible to make a request for change so that adding a filter on the search box is an option.
Hi. I am not an employee of support. You can do this. But I have many years of experience on this forum. I have repeatedly watched the fate of the requests of functions from users. That's why I believe you will learn CSS faster and you can use the first option than it will happen in Helix :).
For a user with skills, this will take 10 minutes. If there is no skills, but you will set a goal to solve the problem, then I think in a couple of days you will be successful.
