Here’s an example:
On this page, http://newlilypad.wpengine.com/product-category/accessory/?orderby=popularity
the applicable css seems to be: .woocommerce .woocommerce-ordering select, .woocommerce-page .woocommerce-ordering select {
vertical-align: top; }
That’s in the Woo Commerce Css file.
I put that code in the regular css file and edited the woo css file.
I tried moving the selector to bottom, and I tried display: none !important.
Nothing makes any difference.
