 * You can adjust where the custom field is inserted by changing the priority,

 * Here are the priorities of the other bits included in the campaign grid widgets:

 *

 * 4 = description

 * 6 = progress bar

 * 8 = donation stats

 * 10 = donate link or read more link

 * 10 = read more link 

 *

 * In this example, we use a priority of 2, which places our custom field before

 * the description, right after the campaign title.
