Hueman Static Page with slider and posts below?

You will need a custom page_template. You could start by modifying the template that contains the slider. Below the slider you would run a new WP_Query and standard Loop. The linked example only outputs the post title, but you can modify this to output anything related to the post that you like.

Note that I know nothing of the Hueman theme. The above mentioned technique would apply to any theme that has a slider on a page template. If one knows how to add a slider to a page template, then the technique can be applied to any theme.

Also note that anytime you want to alter how your theme works, it’s a great idea to create a child theme, otherwise your custom work could be overwritten when the theme is updated.
