Is it possible to attach a custom options page to other top level menus? Specifically, I would like an options page for a post type. I have a custom post type and wish to create an options page for that post type, to configure the archive intro, sidebar, etc. It would make more sense to the user to access the options under the post type, rather than a disconnected settings section.
Yes, it is, you just need to use correct value for “parent” More information here: http://www.advancedcustomfields.com/resources/acf_add_options_sub_page/
For example: if the CTP slug is “my-post-type” the the value of parent would be “edit.php?post_type=my-post-type”
Or if I might plug my add on 🙂 https://github.com/Hube2/acf-options-page-adder
