obligated position

Hi,
I like responsive image gallery plugin, but i have a problem. How can i move the posisition of the gallery? If i put the gallery after a menu, doen′t do what me i’m saying y and always puts in the first place and after, my menu.
Now, i have change my idea, and i put a sidebar for put my second menu. But in phone view, first appear the gallery and down the sidebar, why? how can i solve this? i want first the sidebar and later the gallery.
my wordpress is: https://www.opticaavenida.es/modernas/

Another thing that i want to explain me, is why in the pone, don’t appear the hover information like in the computer. Open’s in a lightbox, i don’t want that, i want like in computer, the over roll.

thanks
