Why does the rich text editor not have basic functionality?
No validation rules: required is a must have,
No label
No styling options
The normal text box clears out all formatting if copy/pasted in from say word, but the rich text box maintains this formatting but what lets it down is the lack of basic functionality.
All components should have at the minimum, styling, validation, label.
Apologies for this, I can make a feature request for styling, validation and label.
In regards to the validation rules, are you using it has a subcomponent of a form component?
The form component does have a checkbox that requires all input fields to be valid, I just did some quick testing and it seems that the query on button click still runs with the rich text editor inside of the form being empty, so just wanted to confirm that is the behavior you are experiencing that needs to be fixed as well!
