Reset values of a select box, separate button or inside select?

Question

I have a filter form with two select boxes to filter results. I've a red button to reset search and view all results, but I'm not sure if I should add "All" at the beginning of each select box?

What are your opinions and why?

Answer 1

If i understand issue correctly you want to select multiple states to filter by. I would probably approach it like this, have a reset button within a dropdown to clear all selected tick boxes:
