Print Checkboxes list vertically

How can I print the checkbox list vertically?

Currently, it is printing horizontally as shown below.

Subject 1 Subject 2 Subject 3 Subject 4 Subject 5

I want it this way

Subject 2 Subject 4 Subject 5

Here is the code I am using to print it.

 <tr>
 <td>
 <form:checkboxes items="${favouriteList}" path="subjects" ></form:checkboxes>
 </td>
    </tr>
