More online users list

[1master1]

this will make the users displayed right after the  "- members online today" text without a line break.
i'm not asking this. if you see yellow circles, they appear because, after 14users display in single or 2 lines, the remaining space doesnt display usernames, and it starts in next line with fresh 14 users list. now i want to display users list uninterruptedly.
i figured out that increasing this value (14) in the code "if ($x == 14)" displays that many numbers without any break. but without setting this value to high, is their anyway that it automatically increases the counter and displays the whole users list?
