Is it possible to add multiple values to one attribute in magento which will be sortable in the layered nav?
here an example :
atttribute "volt" which have : 2V, 6V and 12V
product 1 volt : 2V
product 2 volt : 2V, 12V
product 3 volt : 2V,6V, 12V
so, the layered nav shows the attribute "volt" with 2V, 6V and 12V.....and once you click on 12V, only product 2 and 3 show up. With 2V, product 1,2 and 3 shup up and so on.
do you know how I can get this result in magento?
