There is no single action that will remove the menu from the page, you must identify the menu parts in the code of the page and remove them manually. The different parts are:
The js reference:
This will be the first Menu Writer code you encounter, it will look like this:
<script type="text/javascript" src="CSSMenuWriter/cssmw/menu.js"></script>
Next you will find the CSS references on the page, they will look like this:
<style type="text/css" media="all">
<!--
@import url("CSSMenuWriter/cssmw/menu.css");
-->
</style>
<!--[if lte IE 6]>
<style type="text/css" media="all">
@import url("CSSMenuWriter/cssmw/menu_ie.css");
</style>
<![endif]-->
Finally there is the including of the menu, if it is a dynamic page like php then it will look like this:
<?php require_once("CSSMenuWriter/cssmw/menu.php"); ?>
If the page is static then you will have a div with the menu inside of it, this div will need to be removed. Once you have removed these three parts then the menu will not be on the page.
