If you want to add tabs feature, you'll need to implement tabs... e.g from Bootstrap.
- Instead of saying: 'it's not working', explain the problem in detail.
- Screenshots with the URL visible in them and the problem marked are more than welcome.
- Tell us how to replicate the problem, we can't fix it if we can't find it.
- Make sure that your site/server meets JomSocial System Requirements
- Make sure to setup JomSocial Cron Job
- Always provide us with access details to the backend and ftp. We need it to debug problems.
- If you have a similar problem, but a solution you found isn't working, open a new thread instead of 'merging' with an existing one.
- Use the "Thank You" feature on any post that helped you
Publisher is a component which have his own layouts, you can't use/publish it on another layouts/components.
Issues are parts of publications and they can be published only under a publication.
There is no layout that is tabbed, but maybe using a Joomla programmer you can do some custom changes in component and implement tabs. Be aware that if you do custom modifications then you will be able to update in future.
