1. When I go to list my products I get a huge space (1) and I would like to get rid of the menu (2). The text formating is odd (3) and the text also gets cut off (4)

Is there anyway possible to get the layout to look like the picture below this one? I get that when I edit a product and click "view Product" That formating is how I would like my list to look(2) but with out the extra space to the left of it (1)
