I have a client with a Salesforce Community website who wants to have a pop-up on the homepage, but they only want it to pop up one time per user. This is before they login, so I'm thinking what I'd need to do is drop a cookie on their computer so I know that they already saw the pop-up. Is this possible? Does anyone have any better ideas to make this happen? Thanks!
Edit: To explain further, you'd create a custom component, and place it within your community somewhere. This component would check to see if the notification has already been displayed (via cookie or a key in storage), and if not, display a modal and set the flag so future visits won't trigger the modal.
