There are built-in editors for: posts, taxonomy terms, menus, widgets, medias, general settings. RTL languages support. Hreflang tags generation for multilingual SEO. Known Issues Autosave is not supported for the WordPress releases before 4.6 or after 5.0. Array values(same meta_key for multiple metas in a post) are not supported for the Custom Fields. Array values in the Custom Fields are seldom used, if you do need this, try another approach: save Array values in a field, delimited by special characters.
