WPF scrollviewer scroll without scrollbar visible like Touch but with mouse

i have the problem that i want to make a header Menu like a Menu in a Tablet or Mobilephone. It will look like this but we only see 7 Button and the 8 Button is outside of the viewing area in the Stackpanel.

When i click in the Stackpanel i am able to horizontally scroll by the left and right Keys, but i want that when my mousebutton is pressed, that ich can also scroll through it :D

i don't find enything like this, so i hope that you can help me :D
