RapidWeaver Stacks add-on info:
Show only part of text and have the rest revealed when the Read More button is clicked. You can add a 'more text sign' like "…" or what ever you like to show your website users that there's more to read. Plain, simple, stylish.
Allows you to 'hide' all different kind of content from text, images, buttons to other Stacks.
