Fixed: Needed to use a Textarea only controls do not work

repat commented 5 years ago

Same here. Did you figure out a fix?

jonathanlb commented 5 years ago

@repat It looks like the fix is the element argument to the SimpleMDE constructor should be a textarea element (as opposed to a div).

Is it worth putting a DOM-element type check in the SimpleMDE constructor to avoid confusion for new users? I'd be happy to submit a PR.
