Does anyone know, if there is any work-around or regular setup for panels or custom code known, to be able to use a url/node/%id or node menu-callback to render node/entity content delivered without the rendered page wrapping (&lt;html&gt; &lt;header&gt;,etc)?

I am not asking for Panels_everywhere behavior nor for Drupal modules like Colorbox, Lightbox, and all the others, nor Colorbox_node popup and such. I only try to have the node/entity callback url at hand to render entity or node content without any page.tpl.php or html.tpl.php involved, to use it somewhere else like for bootstrap modal, node_panels rendered into modals, or for custom scenarios to get most flexibility. 

I took a look into Ctools module suite's modal callback and Entity_popup but the lack of documentation (no offense) and the confusion in my mind lead me to here asking for some breadcrumbs and ideas.

Thanks for any help on this.


Question: Why do I get the wrong result from this program to compute gross pay?
Answer: What you are doing is - 


if the person has worked more than 40 hours, you pay him 1.5 times for complete hours worked.
if the person has worked less than 40 hours, you pay him 1 times for complete hours worked.


This works correctly if the amount of hours is less than 40, but according to your question, what you have to do is -


if the person has worked more than 40 hours, pay 1 times for up to 40 hours, and then 1.5 times after 40 hours (that is total hours - 40).
