HI, this is for the list of columns on the left side of the Gantt, called TreeListView. If it would be possible to add additional columns that we select or implement during data binding, for example: Duration, other dates, description that the client will select dynamically, so they must not be a static list of columns.

Thank you,

Hello,

Changing dynamically the columns in the TreeList part of the Gantt chart is possible by using the widget setOptions() method, which is part of its JavaScript API. Note, that such modification could not be done with server code.

Here you will find a small sample of how to achieve the above in JavaScript.

I hope, that this helps. In case you have any other questions, please do not hesitate to contact us.
