Today’s eye-opening realization is to read the documentation. I probably spent 2 hours trying to get two fields side by side. After searching the Google groups, I saw the suggestion and link to the documentation for the plugin. And, of course, the plugin had instructions on how to get the fields to lay side-by-side.
Of course I could also have done it with straight CSS. But there is something to be said about keeping within the plugin environment. For instance, if I decide to delete the plugin, I don’t have any lingering styles in my CSS to worry about.
