This website uses the seemore plugin which makes it possible to only show the start of an entry, and expand to show the full item when a link is clicked. The original version reloaded the entire page but I have modified the plugin to use JQuery so it now expands the item in-situ without having to reload.
It works in a similar fashion to the updated gallery plugin and also needs
to be added to the head section of the webpage.
The updated plugin can be downloaded here.
