The Column Chooser is an element that allows a user to alter the set of visible columns at runtime. To open the column chooser, click the «Column Chooser» button at the top of TreeList. Now, you can drag and drop column headers to and from the TreeList, thus showing or hiding columns. Use the column chooser’s search box to quickly find the required column.
