What it is
A side panel with your size table that opens only when the shopper asks for it - from a Size guide link under the size picker, a button, or a menu item. The page dims behind it; one click outside closes it.
When to use it
- You sell clothing, shoes, rings or anything with sizes.
- The same question keeps arriving by email: delivery times, returns, care.
- You want information one click away without a separate page to maintain.
Why it works
It answers the question at the moment it is asked, without sending the shopper away from the product they were about to buy. Because it only opens on request, it never interrupts anyone and never competes with your other pop-ups.
