Pull-Down Navigation Menus

Pull-down menus are options that appear when the user selects an item with a mouse. The item selected is usually at the top of the list of options. The rest of the options are listed below it, as if you had pulled them down.

Pull-down navigation menus are generally not recommended as a way of optimizing home page real estate, because of the following drawbacks:

Most of the content is hidden
Pull-down menus only display one line of text. The rest of the content is hidden from view, until a user pulls down the menu. This does save space, but doesn't allow the user to view all the options when they scan the page.
No control over the appearance of the menu
For now, you have little control over the font size, color, spacing, and formatting of the pull-down menu. Even if you try and use style sheets, this can lead to problems between different Web browsers!
They require more effort
They are quite small, since they only offer one line of visible text. This makes them somewhat cumbersome to use.
Javascript pull-down menus
Some Web sites use Javascript menus. This is designed to save time by activating the selected option, usually a link to another Web page, without requiring the user to push the activation or "Go" button. However, if the user has disabled Javascript in their browser, the menu will not work
