It doesn’t appear that standard Markdown has this capability. You can:
- Use CSS, by putting this somewhere in your markdown document (note, this will effect all ordered lists in the document)
<style type="text/css">
ol { list-style-type: upper-alpha; }
</style>
- Use an extended version of markdown. Pandoc markdown has a
fancy_listsextension that will allow you to mark lists with letters and roman numerals.
Note: if using capital letters, two spaces are required before the text. See https://pandoc.org/MANUAL.html#fn1
A. the letter A
A. the letter B
A. etc
