#Remarks
The TreeList component displays a horizontal scrollbar when the total width of all its columns exceeds the size of the component itself. Use a column’s FixedPosition property to freeze the column and keep it visible on screen while users scroll the treelist horizontally. The following code snippet anchors (fixes) the Name and Type columns to the TreeList’s left and right edges:
