Hi Shahriar,
Thank you so much for that. However, the PACKAGE SETTINGS tabs are still not working. I tried to do the same thing you did for the ATTACH FILES tabs but it’s not working. I added an ID on the main container of that metabox and added the same jquery code, it’s working fine but the two other tabs are returning blank tab content. I think it’s because of the other included files from package-settings-front.php file that’s responsible for displaying other pane tab contents. I wanted to try and customize it further but I’m afraid there will be other conflicts. I’m hoping you can help with this as well.
Regards,
