WordPress Timeliner is a powerful plugin, which generates a timeline based on events. What is an event? Well, it can be anything with a date stamp on it – a news article, a blog post, a portfolio item, you name it. If it has a date, Timeliner understands it! From the options page you can specify how many posts to get from the database and you can also choose one or more categories to get the posts from. Timeliner comes with two unique designs to begin with, and it’s also easily customizable with CSS.
