Hello,
Example:
http://webix.com/snippet/777ec6d3
The 4th column is hiden (train) but in the contextual header menu the column is indicated as displayed.
When I click on Train (in Header contextual menu) that generate a error (the column is already hiden).
Regards,
You can do it like next

When you are providing the custom list for the menu, datatable will use it as is, without changing anything. So a hidden state needs to be defined as part of the initial configuration.
Thanks
I think that is great if this parameter is added in documentation:
