Sorry, this method is what I suggested. becuase there are pxp between cam
and lcdif, can't use simple minItems/maxItems to limit list.
If put two lists at top, clock-names list have to dupliate at both top and
if-else branch.
If there are better solution, please point me which file have good method
to share two totally difference list.
