I want the left navigation menu to display the categories and subcategories only for selected categories. I still want to display the layered navigation. I added the following to the "Custom Layout Update" but it hides the whole content of the columns
<remove name="left"/>
How do I hide just the category block? I also tried the following but no luck:
<reference name="left">
<remove name="catalog.leftnav"></remove>
</reference>
