Found the solution through Elementor config
Anyway, I have some sites without Elementor just Generatepress, can I edit the viewport width for mobile res?
The theme has two breakpoints for tablet and mobile.
Currently the only control is the Mobile Menu Breakpoint found in Customizer > Layout > Primary Navigation.
The rest of the breakpoints are fixed and are for controlling the sidebars, footer widgets and blog / product columns layouts. GP is not responsible for any content you may add within your pages or posts.
