It's not clear which bit you want to slide, and do you really mean vertical or horizontal?
Perhaps highlight the part you want to slide in red and draw an arrow for which way you want it to move.
Are those the buttons 1. Home Page etc? "Template reel" etc means nothing to me.
There are lots of nice jQuery sliders out there, so just be specific about what behavior you'd like and I'll suggest one I've come across.
