How to embed all Freenode IRC widgets into my website

I have already embedded our organization’s Kiwi IRC widget into my website’s webpage and that works fine.
Is there anyway so that I can embed all of Freenode IRC channels onto my single webpage like Embedding a Kiwi IRC widget into your website, so that if any user want to explore the knowledge through more than one IRC’s then he/she can easily join/access other IRC channels.
