Bootstrap and Bootstrap-Select - Fit Select and other elements to div width, 100% width/height

Question

I have a mixture of problems that I am running into.

1) I am using Bootstrap-Select to get a modern select box with search capabilities, but no matter what I try, I cannot seem to get the select to fill the col-span.

2) I have split the row into 2 columns: 2 (Select) and 10 (Images/Map), but unless I change the the widths from 100% to less, they are overlapping and are being placed on top of each other, instead of left-right.

3) Each image (will be replaced by a map) is set to 50% height and 100% width, but still I see the scrollbar for the browser, and its not a small scroll space either. I want to show the map to full 50% height (each, so 100% total) without the scrollbar. I have a feeling the navbar's height needs to be taken into consideration?

Please use the attached jsFiddle for convenience! Borders are added for column visibility only and can be removed.

When using bootstrap-select it's good practice to use the data-width="100%" to cause the select to fill the space of it's parent i.e. bootstrap column. You can also add this option via javascript when you initialize it. You can read more about that and other options here: https://silviomoreto.github.io/bootstrap-select/options/#core-options

When using either .container or .container-fluid make sure you keep the classes in order: .container .row .col-x-x. Mixing in extra divs that might become the parents of elements you're trying to keep a specific size, might cause problems.

There's a great bootstrap class for images .img-responsive. I would suggest using this for your images. You can read more about that here: http://getbootstrap.com/css/#images.
