Tell us what you are trying to do?
I've set up a one-to-many relationship for Housing Developments -> Voids. I have a view that displays Housing Developments, and in the filter for this view I have a checkbox with the label, "Available now", which matches Housing Developments against a custom field called "properties-available". At the moment, the user has to manually update this custom field to indicate whether the Housing Development has a Void or not. What I would like to do is to make this an automated process. So, if the "Available now" checkbox has been checked, only display Housing Developments which have a corresponding Void.
So the issue is that you will need to create a view listing the voids, then add a filter to that view to show only the available voids.
This in turn will allow you to display the parent title from the void view. To do this click the fields and Views button on your output editor then add the post title and then select the "Post Selection" option. See Screenshot.
From here you can select the parent and it will allow you to display the parent information of that void.
The main issue now is that you will have duplicate housing developments in your listing view because the Housing development can have many voids.
Thanks for your message, and apologies for the late reply. So, the above will give me a list of Developments which have Voids, but I want to initially display all Developments, including those without Voids, and then when a user narrows the search, filter this view to show only Developments with Voids. Is it possible to add a filter in the Search and Pagination section which would allow me to, for example, add a checkbox which, when checked, filters the view so that only Developments with Voids are displayed?
