Hello. Thank you for contacting the Toolset support.
There is no master setting available to change how Repeating Field Groups are displayed. I think it should be added and for that I suggest you should raise your voice by filing a new feature request using the following link:
=> https://toolset.com/home/contact-us/suggest-a-new-feature-for-toolset/
However - I think I am able to find a workaround that will help you to resolve your issue.
Please try to add the following code to your current theme's functions.php file:
thx so far, I tried to use your code snippet and it seems to work for the post-type I´ve used to test it. BUT: When putting the code into the functions.php I can´t edit the post of other post-types anymore?? When deleting the code-snippet everythings works fine again.
ERROR = the link of the post is not available anymore
I´m not that familiar with PHP or JS to find out what happens there. Another question: I´ve use different post-types, and I want only the horizontal view for all, not only a single post-type.
