Hi,

I loaded 3 dropdown fields based on 3 tables with read_data.
The 3 dropdown boxes should now be made dependent. I just wanted to do that in the dropdown boxes under "Events".
What do I have to set?

Thanks in advance.

1. Dropdown / {var:read_data33}
Tabelle1
id_lkr | lkr | landkreise
------------------------
1 | BAR | Barnim
2 | BRB | Brandenburg/Havel
...

2. Dropdown / {var:read_data20}
Tabelle2
id_gem | id_lkr | gemeinde
------------------------
1 | 1 | Ahrensfelde
2 | 2 | Havel
...

3. Dropdown / {var:read_data37}
Tabelle3
id_ot | id_gem | ortsteil
------------------------
1 | 1 | OT Schönwalde
2 | 1 | OT Dumsdorf
3 | 2 | OT Alt Markendorf
...

Hi
In the meantime I have found out myself that it works with 2 dynamic pages and with the right "Where conditions" and "Fields to retrieve".

The dropdown fields work with the names:

1. DropDown
Name: landkreis

2. DropDown
Name: gemeinde

3. DropDown
Name: ortsteil

But the dropdown fields must have this name:

1. DropDown
Name: Marker[landkreis]

2. DropDown
Name: Marker[gemeinde]

How does it work?

Hi Fredolino,
​
As a fix I suggest that you use the names that work and combine the results into an array after the form submits. Does that do what you need?
