This is TreeView Professional as simple as it gets: the background color is set to match the page background and the TextColor is left at its default black. The Font is also left at its default. We've added a border around the applet as well as a SelectorBorderColor, both set to black.

We're also in the default Mode, 'plain' which gives just the outline structure and labels. This menu contains a total of 76 items running to 3 levels.

Below is another example, still in 'plain' mode, showing a few changes of color. In addition, we've added the ExpandAll parameter, set to 'yes'.
