<for end="@{list:getLength}" step=3><TR valign=top> <for bags=list start="@{for:getSuffix}" end="@{int:@{for:getSuffix}+3}"><TD width="@{double:100/3}%"><call>show</call></TD> </for></TR><tr height=12><td colspan=10></td></tr></for>

Master cyclic slave 0To @ {List: getLength}(Length of the schoolbag list), step size = 3That is, three items are displayed in each cycle.
