This article shows you how to set up behaviours and then apply behaviours to draw layers to create dynamic Web pages.  You will learn how to set up draw layers that appear or disappear when clicked, or layers that are draggable and can be repositioned anywhere in the page or within defined limits - it's up to you.  There's no coding necessary - it's all done through Dreamweaver behaviors which combine an event (something that happens on the screen) with an action (what the browser should do when the event is detected). Adding a behavior to a Web page allows visitors to interact with your page and the page to perform important tasks without having to reload the page.
