I'm new to Backdrop and i'm a little bit lost. I've watched videos and read all I can about pages and layouts. What I don't understand how to do is when creating a new page how do I set it up to utilize a layout? I don't see the fields to do this with even after all the videos and articles i've read. They've all described the relationships between the content and the layout, but none have said "enter X into Y". As with any CMS, I understand there is a bit of a learning curve but this just isn't clicking for me.
I'd appreciate it if someone could provide me these details or refer me to an article/video that addresses this.
I don't think you need the visibility condition that just replicates the path field.
Other than that, then yes, that should work. If you want to tailor blocks as you indicated you might want to, you can add visibility conditions to individual blocks as needed
