I just looked at DD Ep61 to remind myself how it works; I haven’t used it yet.
You will need to provide more information on how you have setup the Filter Component and say one of the Container and Text containers to see what the issue is.
Alternatively, you could upload the project (maybe with just that page) to Elements Cloud and then someone may be able to help.
OK. Found this setting too. It’s in the Container/Filter/Enable Filtering/Transition/Slide. And that has to be set for all the containers if you want them to disappear when filtered.
