This page tests the positioning of popup menus defined within other containers. The yellow box is a padded div, the split pane contains two ContentPane's, the lime box is relatively positioned and the pink box is absolutely positioned.

Right-clicking (or control clicking for mac or opera users) in any of these boxes should show a content menu at the cursor.
