Reply To: Buddypress tabs !!
I dont quite understand what you mean tbh about page refreshes when clicking a link or menu item? that is how web pages tend to work in general lol 🙂
However i do understand what you are saying about what you want to achieve, but you have to realize one thing first, if something doesnt work as your brain imagines it to work out of the box it does not mean you cannot make it work that way, as hugo said you should be really looking towards ajaxing certain parts of your website to acheive what you asked (you said you have no idea what ajaxing is yet you only need to type it in google to find out and read a few articles on what exactly ajaxing does to find out), ajaxing basically will let you do exactly what you are describing, you can read about it here https://codex.wordpress.org/AJAX
There are quite alot of wordpress ajax plugins around i have messed around with myself with mixed results when used with wordpress and buddypress, i suggest reading the link above then searching for a few ajax plugins and try them out for yourself 🙂
