Hey JP, You can use the workflow action âElement Actions --> Display Dataâ for this.
Here is a forum example with workflows (there isnât any test data in preview mode at the moment, but the workflows would be similar for your app):
In this example, there is a repeating group of Users on the page. Within each cell of that User Repeating Group is an image element, with the data source âCurrent cellâs Userâs Profile Pictureâ. When that image itself is clicked, a Popup opens which displays that Userâs Photography (list of images) within a repeating group (type: image). To display the most recently-clicked on Userâs photography (list of images), you would set:
-
The popupâs type of content to User (the type of content of the popup matches the type of content of the pageâs repeating group).
-
The repeating group within the popupâs content type is Image, and the data source is âParent group Userâs Photographyâ.
Then create a workflow when the Userâs Profile Picture is clicked:
âWhen Image A is clickedâ:
1st action: Element Actions --> Display Data --> âElement: Popup, Data: Current cellâs Userâ
2nd action: Element Actions --> Show Popup
This workflow action changes the Popupâs data source (which Userâs Photography is being displayed), thus changing the list of images displayed in the popup.
And that should work! If any of this was confusing at all, please feel free to share a link to your app and we can definitely assist with setting this up!
