Frames can be used to divide the window into more sections, within which different documents are loaded below is the HTML for this ( example).

<FRAMESET cols="20%,*">
<FRAME name="menu" src="htmlexamplea.htm">
<FRAME name="main" src="htmlexampleb.htm">
</FRAMESET>

Tag	About
<FRAMESET>	Defines the start of a frameset
<FRAME>	Defines a frame

The <FRAMESET> tag can have the attributes: cols="percentage,*" for columns or rows="percentage,*" for rows. E.g. <FRAMESET cols="25%,*"> (for this) or <FRAMESET cols="15%,*,25%"> (for this). The * tells the browser to use the rest of the window.

The <FRAME> tag can have the attributes: name="frame name", src="path to document to be loaded in that window", scrolling="yes, no or auto" or border="number". E.g. <FRAME name="main" src="main.htm" border="1" scrolling="auto">. The <FRAME> tags need to go in order to define the individual frames from left to right.
