Hey Nitin,  I followed steps mentioned in the above article. Not showing up numerals icon in the list drop down. It is a kind of blocker for me. and ListUtils.js is greyed out in my folder structure.

Hello Nitin, I tried but did not worked. how can I show the roman numerals list option in list drop down so that author can select roman numerals list option.  

Hey Team, is there way to add roman numerals to RTE plugins(AEM 6.5)
