Made dropdown in navbar-expand absolute and assigned min width

[CJ-Pav]

Description

I have this set to only apply to medium to large (in between) screen sizes. Added absolute, forced 200px minimum, limited application to md-lg screens because that's where the problem really exists.

Motivation & Context

The dropdown previously was taking over tablet screens. Simply was inefficient use of screen space. I understand the collapse navbar and it's great, but the dropdown forcing the navbar even lower than necessary for nav items was difficult especially as pages get larger. This way the navbar stays somewhat minimal. I didn't think the visual needed to change for small screens, but in hind sight it might look better to use this update on small screens as well. This could mean there is an easier way to implement this.
