I am currently using the Editor Widget and the Attribute Inspector to allow users to add new features and then update the attributes with the Attribute Inspector.
We have a request to expand the functionality so that users can edit and add features to a related table.
In our use case, we have Sign posts as a point layer and we would like to add the signs associated to the Sign Post to a related table.
Is this possible to edit the related records using Attribute Inspector, including adding new records to the table?
Does anyone have some examples of doing this?
