JavaScript/jQuery TreeList - Column Chooser

The column chooser allows a user to change the set of columns at runtime. It is configured using the columnChooser object and may operate in two modes: the default drag and drop mode and the select mode designed for touch devices.

Set a column's allowHiding property to false if it should never be hidden. For columns whose headers should never appear in the column chooser, set the showInColumnChooser property to false.

JavaScript
$(function() {
    $("#treeListContainer").dxTreeList({
        columnChooser: { enabled: true },
        columns: [{
            // ...
            allowHiding: false // cannot be hidden
        }, {
            // ...
