I’m having trouble running javascript hide/show div using CSS classes, the initial state all the divs are hidden than when i type in the searchBar the name of the recipe (like the div ribs) it show only the ribs div and so far is working, but when i clear the searchBar its show all the div instead of hiding all of them again.
