A little question on the custom fields

Hi! I've got a tiny issue here. This is it :

-I've got a custom field
-When I enter there more text than the template's width allows, the whole "additional fields block" moves just under the picture (see 1st screenshot)

I am wandering, is there an easy/quick way to divide the phrase that goes too long into two lanes, so that the block won't be displayed under the picture, but to the right. (see 2nd screenshot)

Hope my explanations are clear. Let me know if smth. Didnt find anything suitable in the documenation

Thanks!

Thanks very much.
