[Qgis-user] Hide/Show form field depending on precedent field values

[Arnaud Vandecasteele]

Hi Andreas,

Thank you very much.
This was exactly what I was looking for.
As you said, It requires adding a group. This requires an extra step when
you want to control the visibility field by field.
But it works !

Byt the way, I was looking to do this for using this project with the Input
App.
Your solution works as well in Input.

Thanks again,

Arnaud
