Show Thumbnail of all files in a folder and its subfolders

Hi Guys,

I want to set the Filter Panel (Adobe Bridge CS3) to "show all items in this folder and all its subfolders" through Java script on windows.
From UI it is possible by clicking on icon buton present in the filter panel and content panel shows the files from current folder as well as from its subfolders.
Can any one suggest some Java script to do it?
