[Qgis-user] Add Layer Search to Toolbar

[Andreas Neumann]

Hi,

To me this sounds like you want to set up a relation and define forms 
with relation reference and relation widgets (with or without embedded 
forms).

In the project settings you can define relations between tables and once 
you have defined them, they appear in the forms section of the involved 
layers.

But as others have pointed out, you probably want (or need) a proper 
database, like PostgreSQL. If you have setup your relations in this 
database, QGIS will autodetect them and you can directly use them in 
your forms.

Greetings,

Andreas
