Template:Babel-N - Allows any number of boxes. Format: {{Babel-N|1={{user <box1>}}{{user <box2>}}{{user <box3>}}...}}
To specify a custom header, footer, or color add the parameters header=HEADER (default: Wikipedia:Babel), footer=FOOTER (default: Search user languages), and/or color=COLOR (default: white). Adding <td> between two boxes causes a new column to be started at that point. You may also use '|align=left' to cause the box to appear on the left side of the page rather than the default right.
