Any menu that opened near the top of a page in your dashboard was covered by the bar holding the search box. The customer picker on order, refund and booking forms was the one you would hit most often: start typing a customer’s name, and the list of matches could open underneath the search bar where you could neither read nor click it.
It affected every drop-down in every section, at every window size, and no amount of scrolling helped — the bar stays at the top of the page by design, and menus were being drawn behind it rather than in front.
Fixed. Menus now open in front of the bar, and the bar still covers the page as you scroll, which is what it is there for.
