For SpringMvc recently in use for the web project, the project need to use multiple marquee, the code is as follows,






But the problem is, when a multiple-choice, the choice of the background to receive content is correct, (F) and (E) can be normal,

Corresponds to the control in the form of field is an array, use the list also have this situation,
Excuse me, what reason is this? The great god have to solve?

Please the great god,
