Custom CMS php script hotfix

Hello. We need a hotfix on a custom CMS. It's a quite simple shop feature and the task is to list database entries depending on a selection from a dropdown menu, the first option should display entries in another dropdown menu from id=1 and the second one should show entries from id=2 The retrieved and selected entry is then later used to send the given item to an in-game character of the game. While you're at it, I'd like for the searchbox and search button to be resized to match the above dropdown menus and give it a synchronized feel. Also have a pre-made text within each dropdown meny and search box saying what the given item does, for example; in the search box there should be some pre-made text saying "search..." Cheers
