When building nested lists with checkboxes, sometimes you want to have higher level categories that are easy to spot: this is the goal of headings.
If checkboxes in heading would work and render as they do not in headings, it would be useful here.
The following syntax should create a checkbox, and when the checkbox is checked, should strike through the line:
# - [ ] This is a heading with an unchecked checkbox #### - [X] This is a heading with a checked checkbox
It should work with any level of heading. The whole heading should get strikethrough when the checkbox is checked, like it is done currently in non-heading cases.
I use the syntax above, but the checkbox is not displayed, neither is the strikethrough.
This is briefly mentionned too in this thread: Support checkboxes in tables - #40 by ohreallyhmmm
