[Qgis-user] Qgis-Qfield form field value list relation

[Zvara Gábor]

Dear all,

I would like to set up a handy form for a point layer to use in Qfield. 
The goal is to collect protected species occurrence during field 
sessions. I want to collect data of different living being (birds, 
mammals, plants, insects, reptiles, amphibians, funghi, lichens)  And 
also, I have separate lists for each "group" listed above, containing 
the full list of species (two columns, hungarian name and scientific name).

I have two attributes (amongst others, but they are not relevant). One 
is the "group", the other is the "species name". I want the form, to 
filter "species list" based on the values selected in the "group". For 
example, if I select 'mammals' from "group", the "species list" would 
list only the mammals. Otherwise, if I do not choose any value from the 
"group", the "species list" would list me all species from all groups.

-I want both attribute to be a dropdown list.

-I want the species list attribute to be searchable, and completer (Use 
completer function, I know, but don't know if the whole thing could work 
together.

I suppose I will have to merge the separate species lists, and add a 
third column containing the group type (mammals, birds...etc.)

So please, help me out on this. :)

Thanks a lot, looking forward for all your kind help.


Cheers,

Zvara
