What plugin for a table of contents do you recommend?
I have a very long post and I think it would be a good idea to introduce a Table of Contents. I found some plugins that are not tested with the WordPress version, and others compatible, but only with a few active installations. To be honest I don't know which one is better, and especially which does not affect the website speed. So, I need your help.
Please, can you tell me what plugin do you use, or recommend? Any suggestions will be appreciated.
Thank you in advance.
