Hello @ilariamast ,
The widgets are fully responsive in the free mode, as well. I think it is caused by your design template/theme. You should add the code of the widget into a box, which is appropriately sized. Our widget will expand as long as it has space and your template does not fix the size.
So if you mark a properly sized box and insert into it, it will work nicely.
But show me your example and I can check the problem and suggest a solution.
