Sorry for my poor english. Hope you guys know what I mean here. initial my theme the menu will " drop " for an example while visitor come to surf my site and scroll down, the menu bar will collapse , drop too but I don't like and ask the support " edit the code " make the menu static , that means while the visitor surf the site, the menu bar will not " drop " as he/she scroll down I happen to see quite a lot establish site actually using " drop menu " thus I don't know should I ask my theme support change back make my menu drop ? wonder does it make a difference on visitors point of view? Hope you guys know what i mean here.
