You need to put the popular tags widget on the categories sidebar and use the custom css/js from the other thread.
[nodebb-plugin-stockparser] First plugin; how do I add an editable field?
nodebb-plugin-stockparser parses UGC for StockTwit-style stock tickers and replaces them with a link to the stock detail page.
Can anyone point me to a plugin that already has an admin panel page which has an editable field where I can define a URL pattern? TIA
You can take a look at that nodebb-plugin-imgbed one, that's a pretty good example of saving settings too...
