I’m trying to prototype a product card grid comparison feature. The grid is repeater. Each card has rollover and selected modes in dynamic panels. This grid page allows up to 3 items selected for comparison. If the user clicks the 4th one, it will get a popup saying max 3 is allowed, something like that. The idea is to set an upper limit of how many products you can compare at a time. I would like to know what’s the best way to count how many products have been selected/unselected and what’re the items(name, image, etc). These variables will be passed onto a floating bottom tray showing the thumbnails of products selected and there’s a “compare” button which will trigger a full screen modal showing the spec break down of each product side by side.
I suspect I could use repeater data fields to count the “selected” products. But I’m a newbie when it comes to repeater(a brain twister to me), not sure how would I get started. What would be the best way to set this up in Axure? Thanks.
