I am making a website and in it I want to provide dynamic floating menu bar like Gmail(current one). I have searched over internet for it but there i found menu bar whose co-ordinates are fixed.
I mean if menu bar is on center of page and you scroll page a little then menu will also scroll but when menu bar comes to top of page then menu bar is fixed along with the page and will be shown throughout the whole page. For Example see Gmail menu bar having options like move, delete etc.
I need some help regarding this.
