I am fairly new to SharePoint Online and I have a couple questions regarding the filter pane in a document library.
First, when I do google searches I see images of hierarchies in the filter pane so users can click on one level to open the next, then the next until they get to the lowest level showing a very specific list of documents (the filter, I'm assuming, will show all documents at the highest level of the hierarchy when selected, then when a lower level is selected the list is further filtered). See screenshot below for "Market".
What is required to have that type of navigation in the filter pane? I tried creating a term set but the filter is still just one level.
Second, is there a way to get the filters to show in alphabetical order? Mine don't and my users will hate this. See the screenshots attached showing my filters that are not in alphabetical order.
