How to keep CategoryTree stayed opened after going back?Edit

I guess you cannot be serious about spamming this question to heaps of talk pages? In general there are three places to put this: 1. The extension's talk page. 2. the extension's developer talk page or 3. the support desk. The best option is 1. --[[kgh]] (talk) 20:26, 28 April 2013 (UTC)Reply[reply]

Hi, I have posted a similar question but got no answer so I do not have a solution based on CategoryTree. But you may explore alternative solutions based on Extension:TreeAndMenu  :-) --Cornucopia (talk) 15:18, 29 April 2013 (UTC)Reply[reply]
