minor tweaks to website, fix a few bugs

I have a website created using bootstrap. currently when I log in as a user to the site, after a few seconds the the login name at the top right of page will go from "username" to array and I will have to log back into the site. This is frustrating and I need to stay logged in until I log out. Additionally, the current navigation menu is fine, but I need to have a DROP down menu when mouse-over the navigation items for easier navigation, etc. When I login as ADMIN, or hotspot operator, or user, I need the current navigation menu at the top of the page to change to the menu items for the respective users. Currently when a Admin, Hotspot Operator, or User login they have the navigation menu at the top of the page and a menu at the left of the page. I want to change that. I don't like the left side menu. I want it at the top with a drop down menu on mouse-over. Additionally, the footer has to be edited on each web page. I would like the footer to be editable via a footer file and then updated on all the website pages. Let me know your experience and why you think you can provide this for me.
