Hi All,

I would like to create a pop-up for my size chart in my product page (where its written “Size Chart” and such that it opens up a window with the size table and the customer can close it and proceed with the order on the product page itself). I have been unable to find how to do it from existing discussions. Your help and guidance would be much appreciated.
