Hi,
I would like to group my resources in 2 levels, but found only descriptions how to do it in one. ExtJs examples also do not help me. Seems like my finding skills are not up to par. Can you point me in the right direction?
I want something like this (addresses grouped by country then city):
Germany
- Berlin
- Willy-Brandt-Straße 1
2022.07.03 - 2022.08.03: Angela
- Platz der Republik 1
2022.07.05 - 2022.07.08: Sahra
--2022.08.22 - 2022.08.30: Joschka
- Willy-Brandt-Straße 1
- Bonn
- Adenauerallee 139
2022.06.10 - 2022.06.27: Helmut
- Adenauerallee 139
Sweden
- Stockholm
- Birger Jarlsgatan 109C
2022.01.13 - 2022.03.18: Mats
- Birger Jarlsgatan 109C
Best regards
Martin
