Sorry, I was off on Nov 1st and for some reason I didn't get any notifications about your updates in the original thread, I've just seen your comments now.
I just tried this on my local site and it works as expected, in the limited way I described in the previous thread, namely that you can create a View to search the RFGs, but you cannot create a View to search the posts to which the RFGs belong.
So if you have a custom post type Location which has a repeatable field group "Rooms", which includes a field "max-capacity" then you can create a View where the Content Selection is "Rooms", and you can then insert a filter for "max-capacity".
On the front-end that View will display rooms, and you can apply a filter for max-capacity.
That's what I just tested, and it works.
If it doesn't on your site, and you updated to the latest version of Views, then perhaps there is an issue with the filter you inserted.
I'm guessing max-capacity is a number? And you might insert a filter that specifies it is a number greater than or equal to the filter value?
So i can't show for location whose rooms capacity is a number.
I need assistance to make it possible. It is useless to show custom fields to my visitors who searches for location
I'd need a view that shows location instead of rooms
I understand the frustration, but as I said in my first reply to your previous post, it's simply not possible.
The way that repeatable field groups are implemented using a hidden custom post type means that you cannot include fields belonging to a repeatable field group in searches for the post type the repeatable field group is assigned to.
It is currently technically not possible. It could be possible, but that requires our developers to do some additional work on the Views plugin, and that is why I suggested you submit a feature request (at https://toolset.com/home/contact-us/suggest-a-new-feature-for-toolset/) so that the product manager is aware of demand for this and may schedule time for it to be developed.
There isn't any kind of workaround I can offer you.
If you want to be able to search Locations by "max-capacity" then max-capacity must be a direct field belonging to locations, it cannot be indirectly assigned to locations using a repeatable field group.
