Help Info inside an attribute creates a quick link for your customers to view additional information about that attribute. Here's how you can get that set-up:
There's a Help Info box at the bottom of page when you create a new attribute.
Put whatever you need to explain this attribute, images, instructions, clarification, etc.
On the order page, the Attribute will become a clickable link (see below):
Then just click on the link and a modal will open up with helpful information! This modal pops up at 80% of the current screen size, so customers will be able to view all of the information without dragging and expanding the help window!
Also, if your customers need to reference the Help info while they order, they can simply click on the New Window icon in the top left corner of the pop up! This will open the help information in a new tab so that you customer can click back and forth between the help page and the order page.
