According to the documentation, https://bryntum.com/products/schedulerpro/docs/api/Grid/feature/TreeGroup
This feature can be used to mimic multi grouping or to generate another view for hierarchical data.
Unfortunetly I'm not able to achieve the same results as https://bryntum.com/products/schedulerpro/docs/api/Grid/feature/Group#grouping-by-multi-value-fields where I can have the records on multiple groups
Is this not meant the same?
If I take the example https://codepen.io/pen?editors=101 I never get to see the same record twice (at different groups) like the Group#grouping-by-multi-value-fields feature.
Could some one please clarify how to achieve it (if possible), or is the expression "mimic multi grouping" being here missunderstood?
Thanks once again
