CSS/JAVA integration

We have a website currently under development requiring a 'fix' which should not take more than a couple of hours for the right person with the right skills. The requirement is to have a drop down option that, when selected, drops down over an existing slide-show. The following links show the requirements individually, but not as a whole: 1. [login to view URL] This is the slideshow that is to be incorporated into the webpage 2. [login to view URL] This is the main page with the slideshow incorporated but the drop down (from the 'check availability' option) not functioning 3. [login to view URL] This shows the drop down (from the 'check availability' option) working but not including the slideshow. To summarise, the requirement is to get the slideshow and the drop down working together, so that when the drop down is selected (from the 'check availability' option) it drops down over the slideshow, which remains unaffected.
