The new version of Meta Box plugin has just been released! This version doesn’t have many fixes but focus on small improvements to make the plugin easier to use. See the changelog below to see what’s new and update it from now.


  • Add “Select All|None” for select, select_advanced, post fields. Now if these fields is multiple, there will be 2 links below the select dropdown which allow you to quick select / deselect all options.
  • Improvement: Add max_clone parameter which limits the number of clones
  • Improvement: Add sort_clone parameter which allows users to sort (drag and drop) cloned inputs
  • Improvement: Add Polish language. Thank Michael

For max_clone and sort_clone parameters, please refer to this documentation.


  • Prevent warning when post type doesn’t exist (post field)
