title: Creating a multiple column combobox in Java
body: <p>I need to create a ComboBox in Java that will have information in a column on the left and a Checkbox in a column on the right so that a user can select multiple items in the ComboBox. This needs to be a ComboBox because there could be 100 items in the list that may need to be checked but they cannot take up much space on the user interface.</p>
  
  <p>Does anyone know how to do this?</p>
