Hello! I am a total novice, and trying to learn every day. I recently purchased https://www.coffeecup.com/images/miscellaneous/icons/half-deserted-streets---html-editor-theme_en.png, and I am hitting a roadblock when it comes to making the menu links (Home, About Us, services, etc.) into drop-down menus. I have found different sites that provide the code, but no matter where I enter it, it is not functional. I'm not sure if I need to alter the style sheet or enter it somewhere else...please help!

That template is probably set up for static links in the menu. The easiest method would be to use the css menu builder with the HTML Editor to replace the html code, if you are using the HTML Editor.
