I notice that for a custom page type, under Layout, we can add some customization to it. The question is if my list of Authors (each is a checkbox) is very long, is it possible to display the list into 2 or more columns? If yes, how to edit the code below to make that happen. Thanks for help!
<tr class="form-table-group">
<td class="form-table-label-cell">$$label:Authors$$</td>
<td class="form-table-value-cell">$$input:Authors$$</td>
<td class="form-table-validation-cell">$$validation:Authors$$</td>
</tr>
