Hi Aitor,
I'm trying to understand what you are asking?
Are you asking about Rule activity fields? On the Rules tab you can create a rule. At the bottom of the
page you can hit Show Activity Fields and hit Add Field and create a text area with "Rich Text" set to "Yes".
When your rule is activated, a pop-up will appear with a text editor like above and the user can enter text
which can be passed to a workflow using the rule.properties.your_textarea_field.content in the
pre-processor script.
Let me know if this helps or you are you looking for something else?
