Custom Post Type Support

Hi,

I’d request you to submit a issue here: https://github.com/mkrdip/category-posts-widget/ if you’ve a github account (+1 with a pull request).

In case of WooCommerce they already have shortcodes to show products from a specific category: http://docs.woothemes.com/document/woocommerce-shortcodes/

Hope this helps, Cheers!
