storyline_dropdown(indent) — display an HTML drop-down menu containing all the storylines in the archive
This tag generates a dropdown menu (using the HTML <select> tag) of all your storylines.
Storylines are shown as nested, with children indented with a hyphen in front of their names. Grandchildren have two hyphens, etc. The hyphen is optional; the tag's sole argument can be used to specify a character to use instead.
