This is what it looks like:

molinos-search

Here are the explanations based on the line numbers on the new file. It's best if you see the comparison in Split view.

8: The HTML for a Close button (uses the mathematical multiplication symbol).

19: Added "focus" event so that clicking inside the box would show the results (if not already visible and there's something already searched).

21: Searches partial trailing matches. (foo would match foobar but not barfoo)

29-37: Changed the logic here so that the search is shown if 3 or more characters are searched. The result box is shown even before actual results are found. Because:

39: The result box notifies the user that a "Searching..." action is occuring. This prevents an impatient user from pressing Enter and navigating to the search page itself. The user, seeing the message, would patiently wait for the results to appear.

50-52: Instead of hiding, the search now shows "No results" when there are no results. Also: adds "message" class and Close button.

56-57: Having 10 results seemed too long. I truncated this to 7 results only. If you change the number, be sure to change it in line 66 as well.

64-67: Made some changes to the message, as well as added a Close button.

68-69: When there are no more results, we will still show the message "No more results" below. This allows us again to display the Close button.

71: We don't need this anymore.

73-74: This adds the click event handler for the Close button. Clicking it will hide the result box.

78-79: We'll hide the result box if the search term is too short.

84-86: We won't depend on a click on body to hide the result box, because this gives erratic behavor when interacting with the results. Yes, this will mean that the results box will remain open. That's the reason to introduce the Close button.

93: The very high z-index put the results in front of drop-down menus. I changed it to 19, which is just below the z-index 20 of the menus, so that the results are behind the menu, but still in front of most other things.

118-120: Forcing the color because of the bug in mobile view of Supply theme (the color became white).

141-143: For similar reason, forcing the width of image.

144-146: Messages like "Searching..." and "No results" will have a muted gray color.

147-156: CSS styles for the Close button.
