Hi there,
Yes, It is possible to have multi-line tab title, Please follow the steps given below,
Go to edit post/page => Select Text Editor => write the slider name like this name='Overview <br / > Test'
in tabs short-code.
For multi-line tab title you may need to adjust the content position, for that you can add custom style in WordPress Post Tabs Settings => Miscellaneous => Custom Styles => add the following code here
.wordpress-post-tabs-skin-default .ui-tabs .ui-tabs-nav li { height: auto !important; }
If you are using different skin then you can replace the “-default” with your skin name in above code.
Thank you for all your patience.
Let me know if it helps.
Best Regards,
Sukhada,
