You can divide your frames into frames. It is a good idea to be conservative when choosing the number of subdivisions of the browser window. Too many subdivisions can make the content difficult to follow. Below is an example of how the browser can be divided into multiple frames.
<HTML>
<HEAD>
<TITLE>Three Frames</TITLE>
</HEAD>

 <FRAMESET COLS="15%,*">
  <FRAME SRC="demoOptions.html" NAME="options" FRAMEBORDER="1" SCROLLING=AUTO NORESIZE>
  <FRAMESET ROWS="50%,*">
    <FRAME SRC="imageMap.html" NAME="top" SCROLLING=AUTO NORESIZE FRAMEBORDER="0">
    <FRAME SRC="default.html" NAME="main" FRAMEBORDER="0">
  </FRAMESET>
</FRAMESET>
</HTML>
The content of a frame must direct the links to a specific target. The targets are the frame names or special target names that direct the content special locations. For example, some of the demoOptions.html code is given below. The last target _top directs the content to the window containing all of the frames.

<HTML>
<HEAD>
<TITLE>demoOptions.html</TITLE>
</HEAD>
<BODY>

 <A HREF="imageMap.html" TARGET="main"><NOBR>[Image Map]</NOBR></A>
