Multi-Select Drop Down

[neveryonas]

I have created a drop down  as a cart variant. It is a list of available options and the user is to select 5 out of the 15 or so that are available. Is there a way to make it a multi-select?

I am using Joomla 2.5 and VM 2.6

Does anyone have any solutions to this..or maybe another angle? Maybe I am thinking this all wrong.
Basically I need one product and user is to select 5 different options. If someone could at least point me in the right direction it would be greatly appreciated
