Google Chrome and Mozilla not showing all content

[TWilliams]

When I view my website in google chrome or firefox all of my menu plugins and idx broker plugins stop appearing on my home page. Everything looks beautiful in explorer. I contacted my idx co and they mentioned i should delete part of a code. After I deleted the code nothing changed so I put it back. Help this is really hurting my website.

my website is http://BuyBozemanHomes.com

Below is what they recommended
In your theme's style.css file, there is the following line,
/* Dropdowns
------------------------------------------------------------ */

#cat,
select,
.widget_archive select {
background-color: #fff;
color: #333;
display: inline;
font-family: 'Droid Serif', arial, serif;
font-size: 12px;
height: 26px;
margin: 0 0 10px;
padding: 3px;
width: 100%;
}

If you can remove the width: 100%;, it should resolve the issue.

try removing the height and width here

.slider {
  float: left;
  height: 240px;
  width: 660px;
}

Does not look like that did that trick either...
