How to move application tabs in taskbar in KDE?

I was want to know how can one move application tabs in KDE around the taskbar, I can do this in XFCE-taskbar, but in KDE it doesn’t seem to work, I just grab it and try to move right, but it doesn’t move), well, does anybody know where you can setup this? Such a simple function and no, not working? I need a tip.

Try right clicking on task bar, unlock widgets, right click on Task Manager and choose Task Manager settings. There you can choose how to handle the application tabs.

sort and group both to manually

Oh! sorry, that’s easy, my mistake. thank you.
