Greetings from Syncfusion support.
We understand that you want filtering support for TreeView with a
hierarchical data source. Currently, DataManager only has support for filtering
the first level of the tree nodes and doesn’t support filtering of hierarchical
data sources. So this can be achieved only through datasource looping.
As requested, we have prepared an Angular TreeView sample to
perform filtering on hierarchical data. We have rendered the filtered parent
node with its corresponding child nodes. Please see the sample at the link
