In Magento 1.9 RWD theme when using configurable swatches the not-available options for below configurable options is still shown. I.e. basic example: for configurable option 'design' design 1 is only available in packs of 50, 75 or 100. However, 200, 500, 1000 pack sizes are also still shown with just a grey stroke that is made to be displayed over them and it is still clickable. So, is it possible to make magento remove options that are not applicable to above chosen options ?
