SID-00091: Dropdown List Based On Selected Value

I am using the Know.WebForm template and have changed the OperatingSystem field to a dropdown box (type select). I would like to have the OsVersion field to populate in a dropdown box only some predefined values based on the selected OperatingSystem value.

e.g. When I select "OsWin" from the OperatingSystem field, OsVersion would display a list of Windows OS version (95, 98, XP, Vista... ) and when I select "OsLinux" from the OperatingSystem field, OsVersion would display a list of Linux Os version ... etc.

I tried a couple of test using formfield with no luck, the closest support answered I found was called PersistentSelectedValues by ChengappaCB, could you please help and post the correct method to do this?

much appreciate.!

You will need javascript to do that. For an example, see http://www.javascriptkit.com/javatutors/selectcontent2.shtml
