Make a color swatch appear when a variant is choosen

I`ve include a color switch using this tutorial [login to view URL] But i need it to appear only when a certain SKU is chosen (if contains "GTB"). I managed to do it also, but I could not put this to the selectcallback functions, so It only works when I refresh the page. [login to view URL]: <span class="granilite_swatche"> {% if current_sku contains 'GTB' %} {% include 'swatch-lip' with 'Ivory, Hot Pink, Navy Blue, Olive' %} {% endif %} </span> [login to view URL] var selectCallback = function(variant, selector) { if (variant) { $('.granilite_swatche').show(); } else { $('.granilite_swatche').hide(); } [login to view URL]({ money_format: [login to view URL], variant: variant, selector: selector, translations: { add_to_cart: [login to view URL], sold_out: [login to view URL], unavailable: [login to view URL] } }); };
