Reusables do not know what page they are on.

Three ways to communicate with them:

  • Custom states inside the RE. These states are accesible from the page if the RE is somewhere on the page (exception: if the RE is inside a repeating group; if so place a 2nd RE outside of the RG)
  • Url parameters. They can send and can read url parameters
  • Custom events. Create them inside the RE and access them through the action “trigger a reusable element’s custom event” (or something similar)

Hope this helps
