As of July 10, 2024, Klaviyo now supports URL targeting for sign-up forms in Single Page Applications (SPAs), in addition to regular URL targeting. This extended functionality ensures seamless and accurate form targeting for dynamic, modern web applications, allowing you to display specific sign-up forms based on the dynamically changing content users view within SPAs.
However, please note that the "Don't show on certain URLs" option is not currently supported for SPAs, so you cannot exclude specific URLs from displaying forms in these applications.
