This plugin merges ACF tabs across field groups into a single tab list.
Very useful if you’re re-using field groups across templates and don’t want all your tabs to display seperately.
Requires <a href="https://www.advancedcustomfields.com" rel="nofollow ugc">Advanced Custom Fields</a> to work.
N.B. This has only been tested on ACF5 so may not work on the 4.x versions. 
See <a href="https://en-gb.wordpress.org/plugins/acf-merge-group-tabs/" rel="nofollow ugc">this plugin</a> if you’re using older versions of ACF.
