Problem:
The user, wanted to replace the default WYSIWYG TinyMCE editor in the 'user form' toolset with a simple "textarea" to prevent users from inserting formatted text. They were unable to find a way to make this change using the existing WordPress default "description" field.
Solution:
We suggested that instead of trying to modify the TinyMCE editor, cantonB should create a new custom field that supports multiline text. This approach allows the form to display a basic textarea field, aligning with the user's requirements for plain text input.
