A Flash movie in a layer on a DHTML page containing several layers may display above all the layers, regardless of the stacking order ("z-index") of those layers.
By default, browsers place embedded plug-in content, such as a Flash movie or Java applet, on the topmost layer. In older browsers, attempts to place a DHTML layer on top of a Flash layer would fail.
Newer browsers add the ability to layer Flash content with DHTML content and in some cases the ability to use transparent backgrounds in the Flash content (see below). Use the WMODE parameter to allow layering of Flash content with DHTML layers. The WMODE parameter can be 'window' (default), 'opaque', or 'transparent'.
Using a WMODE value of 'opaque' or 'transparent' will prevent a Flash movie from playing in the topmost layer and allow you to adjust the layering of the movie within other layers of the HTML document.
Note: The WMODE parameter is supported only on some browser/Flash Player version combinations. If the WMODE parameter is not supported, the Flash movie will always display on top.

The wmode attribute/parameter
lets you use the transparent Flash content, absolute positioning, and layering capabilities available in Internet Explorer 4.0+. This attribute/parameter works only in Windows with the Flash Player ActiveX control.
Window plays the application in its own rectangular window on a web page. Window indicates that the Flash application has no interaction with HTML layers and is always the topmost item.
Opaque makes the application hide everything behind it on the page.
Transparent makes the background of the HTML page show through all the transparent portions of the application and can slow animation performance.
Opaque windowless and Transparent windowless both interact with HTML layers, letting layers above the SWF file block out the application. The difference between the two is that Transparent allows transparency so that HTML layers below the SWF file might show through if a section of the SWF file has transparency; opaque does not. The default value is Window if this attribute is omitted. Applies to object only. |
