Context Navigation

Changes between Version 2 and Version 3 of Ticket #35471

-              v2
+              v3
 Filtering content on navigation sidebar is useful if there is a lot of content, but unnecessary if there is little content.
 We also received inquiries about users mistakenly typing in the search field and the content was lost.
 We need the ability to make the filtering optional.
+Also, It seems that users of our service are unintentionally making inputs into the search field. We have received inquiries from them stating that their content has disappeared.
+To avoid user confusion, an option to disable Filtering content on navigation sidebar is needed.
