Changing width of List Of Values

Hi,

I've got a list of values in a BI Publisher data model containing descriptions of projectsfrom Primavera that I've assigned to a parameter to allow the user to restrict the projects selected in a particular report.

If I uncheck 'Multiple Selection' against the parameter it sizes the width of the LOV to the maximum project description, however if I check 'Multiple Selection' it gives the LOV the default size and adds scroll bars to see the full description. Is there any way I can get rid of the scrollbars and just size the LOV width to the data ?.

Thanks
