New fields added to the dataset are automatically added to the filter panel, which is exactly what we want. Due to the large number of fields we collapse all filters. However, new filter fields are expanded by default.
Is there a way to collapse new filter fields by default as well?
When you click Expand All / Collapse All, it becomes the default state for new fields. So if you Collapse All, then expand a few fields selectively, then add a new field, that field will be collapsed by default.
