Navigation-Structure...

Hello ! I want to have a navigation-structure on my page like this: The user should see the page (of course) and all the pages, that are on the same level (like its on www.php.net). I want to use frames, because it looks better (thats my personal opinion, please don't question it ;-)) and the user has not to download the menu everytime he watches a page of the same level. Okay. Whats the best way to do it ? I got one big demand on possible solutions: It should work correct with the "Back-Button" of the browser. That means: When changing from one level to another and then pressing the back-button ONCE, the menu AND the page should have the content before. I tried the JavaScript attached, but it didn't work (see down). Any ideas ? Could this done with php ? Regards Martin I tried: frames["Menu"].document.location.href = "JavaScript:top.menu()"; and on every page, I call OnLoad with a function that calls this line. This all works fine with NN, but with IE I got a problem: In NN, you need one push of the "Back-Button" the get to the previous side and the previous menu. In IE, you need two pushes of the "Back-Button" the get to the previous side (since 2 frames have changed). I want the user to only push the Back-Button ONCE.
