Meta Box Tabs Addon GPL Overview:

Meta Box Tabs is an extension for the Meta Box plugin, which allows you to organize custom fields in tabs. The extension supports 3 tab styles with the same UI as in the WordPress admin area. Developers can set it up easily, organize custom fields in meta box better, satisfy the clients in a more user-friendly way.

• No more re-coding for meta boxes. Your only work is adding more parameters for tabs such as tabs’ titles and where each field belongs to. In this way, the UI is really clear and the clients can understand it easily.
• Tabs can have icons. The extension supports all the icons from Dashicons (the default icon font for the WordPress admin area). Besides, you can use an icon font or images if you want.
• To make everything smooth, we use the same UI as in the WordPress admin area. This makes sure there’s nothing that surprisingly appears in your edit pages.
• Tabs can be on top or on the left (similar to what WooCommerce does). You can also remove the meta box wrapper to make the tabs look better (see screenshot below).
• If you need more ways to control how the custom fields are organized, please consider using Meta Box Columns. It allows you to put fields in a 12-columns grid. Both plugins work well together.
