Dynamic number of cells on fixed number of columns

[Danielle]

Is it possible to distribute dynamic number of cells inside a container with fixed number of columns (say 4). What I want to do is something like:\[code\]<div class="container_4"> <div class="cell">Cell 1</div> <div class="cell">Cell 2</div> <div class="cell">Cell 3</div> <div class="cell">Cell 4</div> <div class="cell">Cell 5</div> <div class="cell">Cell 6</div> <div class="cell">Cell 7</div></div>\[/code\]without specifying where the row ends after every 4 cells, this should look like:\[code\]Cell 1 Cell 2 Cell 3 Cell 4Cell 5 Cell 6 Cell 7\[/code\]
