Problem: I would like to use Layouts to design the content area of my site only. My theme is not integrated. If I add the_ddlayout(), Layouts takes over the entire site. How should I modify my site PHP templates to allow Layouts to design the content area only?

Solution:
Only include the_ddlayout() if you want Layouts to take over the design of your entire site. If not, a more standard WordPress PHP template is appropriate:

if ( have_posts() ) : while ( have_posts() ) : the_post();
// Post Content here
endwhile; else :
//your theme's "No posts found" template call
endif;

Also you should not return "true" in this filter unless you want Layouts to take over the design of the entire site:

add_filter( 'ddl-is_integrated_theme', 'theme_is_integrated_with_layouts' );
function theme_is_integrated_with_layouts() {
    return false;
}

Either return false, or remove the filter entirely. By default, Layouts will not be integrated if you remove the filter.
