I made a relation (1:n) between 2 tables. Not every element from the parent layer has a connection with features from the child layer. The relation is made between 'Tipo de Estrutura' Field and 'Est' Field like shown below.
The relation is made correctly. My problem is with the elements that have no relation (Example 'Rocha'). When I open the 'identify feature' of 'Rocha' Element is shown a relationship table with no elements. It is possible to only show relation when exist or hide this connection?
