Hide Date and Duration Columns

Hi, Do you know how to hide the “Due Date” and “Duration” columns? I only want to make only “Task assignee” visible in UI.
Thank you!39%20PM

Hello,
In the column config you can add hide: true parameter:

{name:"duration",   label:"Duration",   align: "center", hide: true },

That feature is available only in PRO versions.
Here is a sample:

You can read more about columns config in the following article:

Thank you for your help. Ramil!
