multiple resources

Can this edition of dhtmlxGantt support multiple resources?

what does it mean “multiple resources”? One line contains one task.

It’s when one task has 2+ responsible resources.
Or tree has a mixture of tasks with different responsible resources, for easier resource management.

Why not - you can implement this kind of structure using our control. Resources in this case would be sub-items in our model. And it’s definitely makes sense, as resource itself has some sub-task assigned to it.
