This is my first time on this site or asking QUESTIONS in any forum so excuse me if I am not addressing my issue well.  I will try to explain the best I can and also THANK any of you that take time to read this.   I have a theme site for a well known karaoke site,  I make hundreds of themes to offer to members for their profiles and personal SONG pages. 
I use my web site (non-profit) to display all my themes in an iframe concept.  A simple MENU to select themes from various categories.  When you enter the site,  you will see I have a  "Select Themes Here" arrow,  which transitions the html web page  and shows a Menu on the left side .   You select a category  and click on it.   This target's the iframe  and the themes will appear with images to scroll.  They appear on the right in the iframe of course.
The issue I am trying to fix?... is the fact the images  are visible over in the iframe?... but the member may not know  they are appearing and they are being left on the menu..  you simply  mouse over to the right and the web page transitions back to normal but i am trying to think of a way to have the page refresh automatically so  there is no confusion after the iframe is loaded?....

I am basically all self taught and i love CSS design and HTML,,  with minor jquery experience.  I do this for fun and totally non profit.  I thought I would find a forum to ask ONE you knowledgeable people if you could simply guide me to some kind of method i could use or insight?.. or if this is even possible.

Basically  refresh the page ( so the menu disappears)  but still load the iframe ?

my link to my site is here....  thank you for your time.
