Display custom post taxonomy in my loop + Fixe tabs from custom taxonomy

Hi, I need a wordpress expert. I have a tab system using my custom post type. Each tab display a specific custom post taxonomy as title - which works fine - and display the specific custom post type. It show by defaut "All" which is good. However, if i click to another tab from a a custom taxonomy - the content of the tab doesnt change - it still shows me all the post instead of the post attach to this taxonomy. Another thing would be in my loop, in the post li, to display some specific custom taxonomy. We can have a chat to speak more in detials and I ll show you the current code, Thank you !
