RestrictionsΒΆ

Here are some restrictions to keep in mind:

  • Post Options array on first level can have only box containers.
  • attr parameter from Post Options first level box containers, is not used. Because boxes are added with add_meta_box() which has no parameter for specifying attributes.
  • Taxonomy Options array on first level cannot have containers.

Note

There are no restrictions for what options are contained in the options parameter. It’s possible to create multi level options: boxes inside boxes, tabs inside boxes, tabs inside tabs, and so on.
