How to make a Flash movie with a transparent background

Often times we encountered this problem. Like in my situation before. I created a menu using jQuery plugin Superfish and added some flash animation at the bottom of the top menu. The problem is: whenever I navigate the menu, the flash animation overlapping it. Wondering how did I solve this issue? Here is how:

The background of a Flash movie can be set to transparent. This allows the background color or image of the HTML page that contains the Flash movie to show through and allows the layering of Flash content with DHTML content.

Publishing from Flash

The HTML for a Flash movie can be created using the Publish Settings feature in Flash. The Publish Settings dialog box provides an option to affect the WMODE setting. The options selected in the Publish Settings will be added to the HTML source code automatically:

  1. Choose File > Publish Settings. Select the HTML tab.
  2. Choose "Transparent" in the WMODE setting to make the Flash movie's background disappear in browsers which support this feature.
  3. Publish the document.


Using Dreamweaver

Follow the below steps, and Dreamweaver will insert the correct HTML code automatically.

  1. In Dreamweaver, insert the Flash movie into an HTML page.
  2. Select the Flash movie in the Design View.
