@ronie Thanks for this. The way you explained this earlier was great, and this simple example you gave was just thing I needed to know. This is information which should be added to the Video Nodes wiki page.
I was having trouble with getting my custom "Genre" submenu to work because I didn't have the right syntax for the "change action" section to have it properly use my custom genre nodes I created.  Thanks to your example I now have it working perfectly.

The goal I've been going for is to create a custom home menu and associated submenus for all "adult" content, and then edit the existing default "Movies" home menu and associated submenues which removes all "adult" content. This way I can more easily keep the two different movie types completely separate (and block none-adult access accounts from browsing through the adult content) in the home menu and all related submenus while still keeping the same standard submenus like "Recently Added", "Unwatched", "in Progress", Genre", "Years", "Sets", etc.  I've also done the same thing with my Movie Trailers by separating them completely out into their own menu with submenues; yet the Movie Trailers can also be watched directly form the main movie by selecting the "trailer" option in the movie's information section.

If anyone wants the layout, along with the smart playlists and custom nodes I've created to get the menu layout in the Aeon Nox Silvo skin just the way I want, let me know, and I'll share it here.

Thanks again...finding out about nodes was the final missing piece I needed to complete my custom home menu layout. Plex could learn a lot form the Kodi Team regarding user customized UI layout.

I would love to see how you did it, though for use with Amber instead of Aeon Knox Silvio. I'm starting to think I need to use a combination of smart playlists and custom nodes like you're doing to achieve the results I want, so looking at what you've got would be a huge help.

Thanks this is super helpful, but I have a follow-up question that I don't know if I asked previously. I've got my 4K and SD/HD libraries split in terms of folders, and I can get the movies to separate properly outside of the "Recently Added", but I can't for the life of me figure out how to split the TV shows apart so that the both have the metadata AND they are separate. Were you able to do something similar?

Good afternoon @Offsprin .  Sorry I'm just now seeing this message. I had a busy summer.
If you haven't already got this figured out for yourself, regarding your statement, I'm assuming that you want to separate out your SD (standard def), HD (high & full high def) and 4K (ultra high def) TV Shows content each into their own main menu item. If that is the case, you should be able to go through by way of using nodes and/or smart playlists where you utilize the "video aspect" and/or "video codec" rule fields to break up your TV Shows content those various buckets.

Thanks
