This is part of what you currently have: Navigation You add another data field so it looks like this: Navigation Then, in your site's CSS, add something like: -
 * 1) ifexist is considered an expensive parser function. That means that it requires a lot of data/data processing from the server. As such, to avoid use of this function from bogging down the server with tasks, only a limited number of them per page are actually processed. In your case, you are not likely to reach that limit so that part doesn't apply to you. The second reason #ifexist is not recommended is because of the issue it causes when listing wanted pages. Because of the way the function works, any page that you check for will be listed under wanted pages; even if it actually exists. So, let's say you have "Chapter 1", "Chapter 2", and "Chapter 3" with the infobox on each. If you access the list of wanted pages for your wiki, you will see "Chapter 0", "Chapter 1", "Chapter 2", "Chapter 3", and "Chapter 4" even though 1-3 actually exist (and I am pretty sure you don't need a "Chapter 0"). If you never need to use this list, I guess it isn't much of a problem. However, let's say you want to figure out which chapters are missing and you have 200 chapters; all 200 would be listed as wanted. Which ones are actually missing?
