I am building a plugin that has a custom menu with pages under that menu. A few of those pages are custom post types. I would like to have the main menu stay open when I am on one of those custom post types. Is that possible?
Here is what the menu looks like when I'm on a non-custom post type page:
But when I click on Makes, Models or Types, the "Squirrels" menu closes because those are managed by the custom post type system.
Sorry if this is a duplicate. I looked through some similar questions but didn't see one that had exactly this same issue.
