Hi,

The solution to this problem is a bit complex, but here you are: https://codepen.io/Svetoslav-Borislavov/pen/yLxeqVP
You should save the removed tab details and its index in the tabs then remove the tab at that index from the tabs element.
When you want to show the tab again you should insert the tab in the smart-tabs element.

I hope this helps you resolve the problem, if not, do not hesitate to contact us!

Best Regards,
