I have a page with a websplitter on it.

In the left hand pane I have some text boxes and drop down lists.

In the right hand pane I have a drop down on top of a datagrid.

When I have compatibility mode turned off all of the objects display properly, but when it is turned on the dropdown containers are no longer on the bottom of the dropdown box.  The pictures below is of the dropdowns in Compatibility View

This shows the filter control of the webgrid

On pages without the splitter all of these controls function normally.  Can someone tell me a work around/fix?
