FeatureGroupSubGroup: nth level subgroups

Describe the bug
I am using quite a few levels of recursion to generate a map that has subgroups within subgroups, and im not sure how to fix the issue, or if there is a better method.

To Reproduce
theres alot going on here... the repeated for loops are to keep the buttons ordered by hierarchy.

df['Result'] = (~df['Impounded'].isna().astype(int)).apply(lambda x: _results[x])
df['Interval'] = (datetime.now() - df.index).days
df['Weekday'] = df.index.weekday.map(lambda x: _days[x])

Expected behavior
When all button conditions are met, points will display,

Environment (please complete the following information):

• chrome
• jupyter notebooks
• vs code

Commencez par la construction FeatureGroupSubGroup fournie et le TESTING.html généré dans la reproduction Jupyter/VS Code ; vérifiez si les sous-groupes imbriqués au-delà d’un niveau sont représentés et activés comme prévu. Définissez le comportement souhaité pour le niveau n et confirmez-le avec une reproduction minimale sur une carte, y compris la condition indiquée d’affichage des points.
