hi

I would like to replace the "continue shopping" button  (modal.tpl) with a href with a link to the product category

{*<button type="button" class="btn btn-secondary" data-dismiss="modal">{l s='Continue shopping' d='Shop.Theme.Actions'}</button> *}
			 <a href="****** link category Pruct ****" class="btn btn-secondary"><i class="material-icons">&#xE876;</i>{l s='Continue shopping' d='Shop.Theme.Actions'}</a>
              <a href="{$cart_url}" class="btn btn-primary"><i class="material-icons">&#xE876;</i>{l s='proceed to checkout' d='Shop.Theme.Actions'}</a>

example  

              <a href="{$cat_url}" ........

thanks
