This is a very special sample that demonstrates how to create a frame-less layout that works and behaves just like frames.
Here's how it works:
The layout is built using a table. The three blocks that you see here are
actually three cells.
The main cell, this one, includes a DIV.
Then, we use a very simple javascript-based function to load the content from
other documents into the DIV.
This is done by calling the loadContent() function and passing, as a parameter, the path to the file that we want to load into the DIV.
Click the different options in the menu to load different documents into the DIV.
