Hi kaltura,
Unfortunately the ‘smart-docking-layout’ doesn’t support dragging the entire ‘smart-docking-layout’ component to be inserted into another ‘smart-docking-layout’ component.The best option is to drag ‘tabs’ from one docking layout into another as I mentioned in my previous post although you mentioned you have some API conflicts using the provided code snippet. If the option for drag and drop a ‘tab’ into another docking layout suits your purposes you can share some of your code to help you solve the API conflicts you mentioned.
Please, do not hesitate to contact us if you have any additional questions.
Best regards,
