This option works for menu, but you use woocommerce widget here http://prntscr.com/gnx2r8 http://prntscr.com/gnx2uq, I’ve added menu widget into your custom sidebar http://prntscr.com/gnx47y but stylings of this element are different http://prntscr.com/gnx4ol Please check. if you want to use category element, you may add this code in custom css http://prntscr.com/gnx7f2:
.home .widget_product_categories.sidebar-widget ul li:first-child a:before { font-size: 16px; color: #999; font-family: 'FontAwesome'; display: inline-block; content: "\f2c1"; margin-right: 10px; }
