How do I add videos in the Product Description field?
If you are inserting a youtube video, click on "Share" and "Embed". If you are adding videos from elsewhere, make sure you create the necessary embed code using iframe tags. In the Product Description field, click on the "HTML" icon and insert the HTML embed code of the video. Make sure you turn the HTML Source Code mode on before saving by clicking the HTML icon (if you are not in the HTML Source Code mode already). Alternatively, copy the portion of the video URL starting at "//www.youtube.com..." (without the quotation symbols) and paste into the "Video URL" section in the "Other Details" tab when adding your product.
