Removing an Item from Magento's Admin Panel Navigation

Question

Using the Magento Ecommerce system, is is possible to remove an item from the Admin Panel Navigation menu? More generally, is there a way to use the config override system to remove existing elements from a configuration?

I know I can add to the navigation with an override that looks something like this

<?xml version="1.0"?>
<config>
    <modules>
        <Company_Module>
            <version>
                0.1.0
            </version>
        </Company_Module>
    </modules>

    <adminhtml>
        <menu>
             <cms translate="title" module="cms">
                <title>The CMS</title>
                <sort_order>70</sort_order>
                <children>
                    <foo translate="title" module="cms">
                        <title>Foo Item</title>
                        <action>adminhtml/foo</action>
                    </foo>
                </children>
             </cms>
        </menu>    
    </adminhtml>
</config>

but how would/could I completely suppress the CMS navigation item?

Answer 1

Cleaner way to do this:

Add a adminhtml.xml (e.g. to an existing modules that keeps all other customization stuff, or create a new module)

<?xml version="1.0" ?>
<config>
    <menu>
        <xmlconnect>
            <disabled>1</disabled>
        </xmlconnect>
    </menu>
</config>

Answer 2

You could inject a bogus module dependency into the menu item in your config.xml.

In your case,

<adminhtml>
  <menu>
    <cms translate="title" module="cms">
      <depends><module>HideMe</module></depends>
    </cms>
  </menu>
</adminhtml>

I don't think Alan would still need anyone to ask this question, but for anyone else that might end up reading this, it would be a bit better to use:

<adminhtml>
  <menu>
    <cms translate="title" module="cms">
      <depends><config>some/configuration/flag</config></depends>
    </cms>
  </menu>
</adminhtml>

For a specific menu point you can use:

<?xml version="1.0"?>
<config>
    <menu>
        <customer>
            <children>
                <online>
                    <disabled>1</disabled>
                </online>
            </children>
        </customer>
    </menu>
</config>
