If the TreeList contains many columns, they may exceed the width of the widget and cause horizontal scrolling. At the same time, some pivotal columns should be on screen no matter how far the TreeList is scrolled. Such columns can be fixed to the right or to the left of the TreeList using the context menu appearing when a user right-clicks a column header.
