Add this class
list-type-inline to a Rich text or other modules with an unordered list and plain links (like the Post Listing module or Post Filter) to place them inline, removing the bullets and adding some space around each list item. Please make sure your module contains only links in an unordered list.
A lot easier to use is an Act21 List module that has all these options built-in, so classes are not required there.
If you use Rich Text make sure to use a recognizable name for your module. It may be hard to edit inline in the Page Editor, due to its design. You will most likely need to find the module in the sidebar on the left.
Alternatively, you can use an Act21 HTML module, with a coded list, like this:
<ul> <li><a href="#link1">Link 1</a></li> <li><a href="#link2">Link 2</a></li> <li><a href="#link3">Link 3</a></li> </ul>
