I am very(!) unsure, if I understand correctly.
Look at this sample .muse file: https://www.dropbox.com/s/ppe3kgcr9yqr9wj/menu-colours.muse?dl=0
Is it this, what you are looking for? If not please describe in simple, clear words, what you are intending to achieve.
Really don’t understand, what you want. Did you preview my sample site in browser?
If you can’t explain your issue more explicitly, I can’t help …
I want the menu's attributes (in this case - the red color) to appear also on the child pages...is this so unclear?
Just look at the picture I attached in the early post.
Yes, this is unclear! You want the same colour on parent and all its children, independent of its actual state? Just define it this way. Look at this second example: https://www.dropbox.com/s/f37gm6jbm6o5iuf/menu-colours_2.muse?dl=0
Not quite, see here:
I want to create basic orientation: I choose the red category on Parent 1, and moved on to a Child page. I want the red to stay red. I do not want the green there, as it belongs to another category (parent 2).
I guess I am asking something that is impossible.... but I thank you for the help anyway.
I don‘t understand , what you are talking about!
According you description, my sample works precisely, as you intend.
Showing the plan view again and again, doen‘t help at all.
So, if you don‘t post any substantial insights, what’s wrong with my sample, it won‘t make sense for me, to keep answering.
