Flash objects normally appear above all other objects on a page, and they will cover a DHTML submenu. To see an example, mouse over the menu item below and the submenu should appear behind the Flash object (the spinning globe):

The Sothink DHTMLMenu program provides an option to auto-hide a Flash movie or other ActiveX object (Global Settings - Advanced), but it completely hides the Flash object. Here is an example of the auto-hide option:

Most developers do not want to completely hide the Flash object, so here is a method to display a submenu over a Flash object that has nothing to do with DHTMLMenu.Do not select the option to auto-hide a Flash movie or other ActiveX object (Global Settings - Advanced). Instead, add the following parameter to your SWFObject script:

so.addParam("wmode", "opaque");

If you are not using the SWFObject script, add wmode="opaque" to both the <object> and the <embed> tag. Here is the code along with an example (the code you need to add is highlighted):

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,29,0" width="100" height="100">
<param name="wmode" value="opaque" />
<param name="movie" value="images/http://yourdomain.com/flashobject.swf" />
<param name="quality" value="high" />
<embed src="images/http://yourdomain.com/flashobject.swf" quality="high" wmode="opaque" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" width="100" height="100"></embed>

You can see how that works in the following example:
