Ive created a list of 25 options for a product, all colour choices, where they might want to pick more than 1 option (eg some reds, blues or greens in the same piece of patchwork), so they are displayed as advanced checkbox.

When they are displayed on the site they show as a long list of 25 options which run down the page. It looks silly and is unwieldy.

How can this be adjusted to something a bit more sensible?
