Hi Ahmed,

I suggest you set the width in percentage. Also you can acquire a Responsive style of web design by doing so.

Thanks,

thanks  shinu for your replay ,but if i set percentage like 75% control take percentage from number of item in control 
if i have 20 items so  control will appear 15 item and that will expand page width .
how can i acquire Responsive in this case?
