how to add action item in description field at Rule builder?

[Ahmed Abdou]

I am trying to add a check list to review tasks ... but I can not find the correct syntax to the action item (check box). 
I have used all these syntax, but not one of them renders as a check box.

Hello @Ahmed Abdou 

There are currently no wiki markdown codes for adding Action Items to rich text fields like the Description field.

Refer to the original article about Action Items where this topic has already been discussed.
