Currently, as far as I know, to „tick” the checkbox in the preview mode, you have to switch to source mode, find the checkbox, replace space with x, then go back to preview. Is there a way to automate this? Maybe there are plans to add such a feature?
The rendered MD is HTML. I don’t know if it really shows checkboxes or only something that looks like them. In any case, there‘s no way to „reverse“ render an HTML to MD, which would be needed to make changes stick.
And MD does not provide for
input elements. So, no, you can’t check checkboxes outside of the edit view.
