To create a mobile version of your website. Duplicate the layout you currently have on the page. Next, modify the columns of the page you'd like to only appear on a mobile device. To modify a column, select the one you desire and then click on the pencil icon in the center.
Third, click on the tab that says Responsive Options. Finally, click only on the mobile icon since this is the version we want to appear on mobile.
Do not forget to go back to previous columns and disable the desktop columns from appearing on mobile. You don't want two copies of your site on a user's cell phone.
