A lightweight framework for easily adding meta boxes to WordPress plugins and themes.

Field types included:

• Single-line text
• Paragraph text
• Radio buttons
• Checkboxes
• Select and multiple select (uses jQuery Select2)
• WYSIWYG (uses WordPress native editor)
• File upload (uses WordPress media uploader)
• Date picker (uses jQuery UI datepicker)
• Color picker (uses WordPress Iris color picker)

More fields could be added in the future, but one of the goals of this plugin is to stay as lightweight as possible.

ATG Meta Box can be used as a standalone WordPress plugin. The files can also be included directly in other plugins and themes.
