Make it work with a third menu?

Sure, that’s possible. It’s a small plugin & straight forward – https://github.com/copyblogger/genesis-simple-menus/blob/master/simple-menu.php

Thanks.

I kind of got it to work – but it raised a related question. When you choose to display a particular menu for a category, does that apply to sub-categories and posts that have that category (or a sub-category) as well?.

Basically I want to choose a blank menu universally (top level of the site) and then for each category (and its children) and all posts that have that category have it use the menu selected.

I’m kind of in the dark.

So I’ve gone further with this and it seems that due to the fact that any post can have multiple categories, I have to explicitly select the menu for each post and sub-category.

I suppose it’s possible to do this in php but that’s clearly beyond the scope of this plugin and this support forum.
