Nice theme but how it may be possible that the usual product pages can not be made in full page, but it requires the template manager. I would like so that I have the top slide and the full width of the basic text, and below 2/3 products and 1/3 page next to the bar. but I do not want to do this with the template manager
You can create a full width page with a slider shortcode in the Free Code Space for Advanced Users and use the product shortcode in the page body content. However in a full width page you can not have a sidebar.
there is no combining. Maybe the only solution here is to use a full width page with columns with product shortcode and a coulm with shortcoded sidebar for which you need a plugin which can support a shortcoded sidebar anywhere in a page.
I dont understand why you dont want to use the template builder as it is one of the great features of this theme.
