if you want to remove the dropdown sort option you shall open your theme functions.php and add following line:
remove_action( 'woocommerce_pagination', 'woocommerce_catalog_ordering', 20 );
in general, is it possible eliminate elements from your woocommerce design using a remove_action.
In woocommerce plugin is a file called woocommerce-hooks.php inside this file is listed all elements of the various elements of the wep-shop-pages, which all can be removed this way.
Just find line add_action line you want to remove cope the line into functions.php and overwrite "add" with "remove".
I have created a woocommerce webshop using a standard theme.
I preferred to work with Weaver ii because of its flexibility, but this was actual a hindrance to achieve my goal, so I shifted to TwentyEleven. But also this theme had some issues especially with the sidebar widgets during the process.
So once again I changed theme. Twentyten makes no problem with widgets. Instead I modified the CSS to the result I wanted.
(I have now renamed the theme, so it wont disappear when updating.)
