In order to have HTML elements on top of Flash movies, you need to include the parameter - wmode="transparent"- in your <embed> element. We use HTML elements for our dropdown menus and we generally want them on top of any content on the page.

If you also have an <object> element, you can add <param name="wmode" value="transparent" /> inside that element.

For wmode to work properly in both IE and FF an attribute should be in both a <param> and the <embed> tag.

For example:

<PARAM NAME="wmode" VALUE="transparent">

<embed wmode="transparent" src="flash/hello.swf">
