Remove attribute label displaying under Layered Navigation

Question

short :

Attribute have many dropdown values - v1,v2,v3,v4

IF all Products are assigned to value "v1" of an attribute , means no products are assigned to "v2,v3.v4" than that Attribute label should not visible under Layered Navigation....

Long :

we wanted to hide one attribute value in layered navigation.

many attribute codes have same attribute value.

ex: "attribute codes "a1", "a2", "a3", "a4" have attribute value "v1"

we are using following code to hide the attribute value "v1" in layered navigation.

but Attribute Label is still displaying in layered navigation.

if for attribute code : "a1" , attribute label is "L1" , values are "v1", "v2","v3"

if all products are assigned to "v1", than along with "v1" , I want to hide "L1" in layered navigation.

As per my understanding, below solution would resolve your issue:-

Please copy app/design/frontend/base/default/template/em_layerednavigation/view.phtml template file(em_layerednavigation folder) and place it in your theme and append below code after line number 49:-

<?php if($this->__($_filter->getName())=='L1'&& $_filter->getItemsCount()<=1)
   continue;?>
