Help about PHP and JScript

[mp3lab]

Hi

I need a HUGE help, because I am new to PHP and do not have much experience.

 

I need help regarding PHP and JScript, iframe

I have a page with html and iframe

navigation links are on the side and top, and everything opens in the iframe to the right side of navigation.

example:

HTML: http://www.bikeshopkompas.hr/test/index.html

And it works almost OK

I do not know why the thumbnail viewer displays the image only within the iframe?

 

For sidenav I used http://www.stunicholls.com/menu/tree_frog_vertical.html

 

and for thumbnail viewer http://www.dynamicdrive.com/dynamicindex4/thumbnail.htm

 

but I tried to make the entire page in PHP, and now it works almost well

but I want sidenav to works as in the example with html

 

I want Sub level to remain open until I click on top level

example with PHP

PHP: http://www.bikeshopkompas.hr/test/index.php

 

question:

How to make that sidenav works as in the example with HTML

I want to change contents only inside  "Maincontent" div?

 

I apologize for the bad english but I'm not the worst
