Magento – How to Hide Attribute Label in Layered Navigation

edit the file /app/design/frontend/{package}/{theme}/template/catalog/layer/view.phtml and replace this line:

 <?php if($_filter->getItemsCount()): ?>  

with

 <?php if($_filter->getItemsCount() > 1): ?>

I only see one problem with this approach.
If all your filters have only one option they you will still get the section title

<p class="block-subtitle"><?php echo $this->__('Shopping Options') ?></p>

But this can easily be overcome if you loop through the available filters and see if you have at least one that has the items count bigger than 1.

The link you have posted is the correct solution.

You will need to create a local.xml file in your theme in the following directory.

app/design/frontend/yourtheme/yourpackage/layout/local.xml

You can then unset and set the block you wish to reposition.

 <?xml version="1.0"?>
<layout version="0.1.0">
    <catalog_category_layered>
        <reference name="left_first">
            <action method="unsetChild"><alias>catalog.leftnav</alias></action>
        </reference>
        <reference name="product_list">
            <action method="insert"><blockName>catalog.leftnav</blockName></action>
        </reference>
    </catalog_category_layered>
</layout>

After you have added your local xml and xml updates make sure you clear all Magento caches.
