Under the repeating group’s data source, I’ve set it to the feed and it’s sorted by a feed’s property that I’ve selected. In this case, it’s the pubDate, which is the date:
This works when I switch it out to sort by any other property from the feed (ex: alphabetically by title). By that logic, I added a dropdown field and a Sort button so the user can change the order to their preference:
Back to my repeating group, I set the sort property to be dynamic based off of the dropdown’s value:
However, I’m not sure how I can get the repeating group to refresh with the new sort property when I click the Sort button.
It would be helpful if you created a test app and then published the link to the editor here. I’m sure the Bubble team will eventually change this (if they haven’t already), but up to this point you have to change some data inside the data set that you are defining for the data source of the repeating group. If the data you are calling remains unchanged, despite a new sorting property - I believe the repeating group does not refresh.
