Hello,
The promo box lets you control the different borders around the box. To add the orange ribbon, this can be done with some CSS. Here is an example with the CSS inline for the ribbon:
[intense_promo_box border_left="1px solid #cccccc" background_color="#fff" border_top="0px solid #ccc" border_bottom="0px solid #ccc" border_right="0px solid #ccc"]
<h2 class="ribbon" style="margin-left: -10px; box-sizing: border-box; margin: 20px; height: 30px; width: 100px; color: #000; font-size: 16px; text-align: center; line-height: 30px; padding: 0 10px; position: absolute; left:-15px; background-color: #ffba13;">
Our Pick
<div class="fold" style="bottom: -9px; border-width: 9px 0px 0px 10px; border-color: #b6830f transparent transparent; box-sizing: border-box;
position: absolute; left: 0; width: 0; height: 0; border-style: solid; color: #fff; font-size: 30px; text-align: center; line-height: 40px;"></div></h2>
