The problem is not on creating, but on page resizing, when i load the page as desktop and then I scale down, the elements of desktop hide and the mobile ones do not appear and vice versa, when I load page on small window and then I scale up the mobile elements hide but the desktop and tablet ones do not appear.. If you want I could send you an user but i think you can't do anything. I think it's a problem of WPBakery, I could try to make a script which reload page on resizing above and below a limit. You could try it on a test site with WPBakery.

The test is creating 2 elements, one only for mobile and the second for desktop and tablet, and then you try to resize the window, you will see what I'm talking about. I think it's a common problem, because there are no options to modify parameters. If it works on yours I will give you the user, because till tomorrow I'm not on computer.

Thank you

Hi I want to create a new homepage, I want to use different grids for desktop/tablet and mobile version, when I load the page on computer and then I scale down the page, the grid for desktop/tablet hide, but the mobile ones does not appear, is that a theme problem? How can I do? Is there an option to use?Thank you.
