Try Exposing Options instead of hiding them.
Each pull down menu that you use, hides a set of actions within which require effort to be discovered. If those hidden options are central along the path to getting things done by your visitors, then you might wish to consider surfacing them a bit more up front. Try to reserve pull down menus for options that are predictable and don’t require new learning as in sets of date and time references (ex: calendars) or geographic sets. Occasionally pull down menu items can also work for those interfaces that are highly recurring in terms of use - actions that a person will use repeatedly over time (ex: action menus). Be careful of using drop downs for primary items that are on your path to conversion.
