Minimizes the comment list and turns the comments title (eg. "3 Comments") into a trigger to view/hide the comments.
Requires no template hacking, only a knowledge of CSS selectors:
- The comments are usually inside a list with a class of ".commentlist" so you probably won't need to change the option for the "contents".
- The comments title however may be different on your theme so you may have to change the "trigger" option to something different than the "#comments-title" id. Use "Inspect element" on your post's page to deterime the correct class or id of the element you want to be the trigger.
