a parallax animation full screen (left to right), not as a post-squared, in position I want, so ‘as it appears now in your demo on the home page. There is a short code?
There’s no shortcode for parallax slider. Though, adding a slider through a shortcode; the slider will be post-squared. In order to add slider by a shortcode; please go under any page or post and click on the short code button (see: http://prntscr.com/9wpqjs ) you can choose any slider.
However, in regard to add full wide parallax slider on any page; please go under Appearance -> Theme Options -> Parallax Slider -> Slides (see: http://prntscr.com/9wq2ew). After adding the slides in slides field; go to Appearance -> Theme Options -> Parallax Slider -> General (see: http://prntscr.com/9wq2tk), if you don’t wish to show the slider on homapage then select the second option “Manually select in a Post/Page”. Then go to your any page or post edit page where you want to show the slier and go under the ‘page options’ and select the parallax slider (see: http://prntscr.com/9wq4dz ).

Hope this helps.
