<p>The plugin looks up the sub-attributes in your product, then for each value it looks up its parent and adds the parent attribute and the parent value in the product.<br />
When using a filter with the main attribute on the store page, all the products that have that main attribute are returned, which are the same products that contain the associated sub-attributes.</p>
<p>Important:<br />
You can’t create multiple hierarchy levels, just one.<br />
Two diferent attributes cannot contain the same sub-attribute.</p>
