In our sign-up form I want future subscribers to select their field(s) of interest. So I can segment our mailing list using these criteria.

Is there an alternative for the Multiset picklist? I'm pretty sure that our readers will be able to select all three of the options. Or the ones above and below each other.

But I'm also sure that some of them will not be able to select 1 and 3 (see attachment). Because to do so, they'll have to press Ctrl + Caps Lock and then click.

So is there a more user friendly alternative to this picklist? Multiple checkboxes for example?

Thanks in advance!
