Thanks. That worked for the Friends List question. But, as you can see in the screenshot below, Make changes to Event is not an option.
The “Type of content” of the page where the Repeating Group is located is “Event”, so I am especially confused why “Event” is not an option in the Workflow screen.
Btw, you should click on Make changes to thing on your screenshot above and select “Current Page Event” in the Thing to Change field of the action configuration
How would I introduce features to alter the state (the “condition”) of the SELECT and SAVE buttons depending on whether the User in the current sell is a User in the Event or is a User in the logged-in User’s Favorites/Friends list?
You can put a condition on the Select button such as:
When Current Page Event’s Participants contains Current cell’s User -> button is not clickable (for example)
In the same way for the Save button:
When Current User’s Friends contains Current cell’s User -> this button is not clickable
Alright so instead of making the buttons not clickable, change the texts to Remove (or anything else you want)
Then build 2 workflows for each button. Here are the ones for the Select button
When Select is clicked and Current Page Event’s Participants doesn’t contain Current cell’s User -> Make changes to Current Page Event: Participants add Current cell’s User
When Select is clicked and Current Page Event’s Participants contains Current cell’s User -> Make changes to Current Page Event: Participants remove Current cell’s User
