[Lizmap] conditional forms

[Etienne Trimaille]

Hi,

Thanks for taking some time to debug the issue.
I'm not very able to review this side of the code unfortunately.
Maybe better to raise the discussion on GitHub ?

Can you also confirm which Lizmap version and QGIS Server/Desktop ? with
patch number included.
