XF 2.2 PHP callback widget help

[alternadiv]

I don't fully understand PHP callbacks but I've been trying to learn how to use them because I think they can be pretty handy.

What would I have to input to create a PHP callback of the public navigation links? I'd like to be able to create a column sidenav that displays the links that would typically display in the main sticky nav.

 

[alternadiv]

I thought it might be something like

XF\Pub\App::getNavigation

but that's not it.

 

[alternadiv]

I figured this out without using callbacks. I can explain it if someone else wants to achieve this.

Would love to learn more about this. Can you share?
