Ok, so I see a few things in my research. One is that this is harder to do than I thought, and the other is that the CSS3 Columns command is more commonly used nowadays than I thought:
BUT I still can't get it working! Can it be used with toolkit? I'm trying this with no results:
.locations .wpcf-form-item-checkbox {
-moz-column-count: 3;
-moz-column-width:200px;
-moz-column-gap: 20px;
-webkit-column-count: 3;
-webkit-column-width: 200px;
-webkit-column-gap: 20px;
column-count: 3;
column-width: 200px;
column-gap: 20px;
}
My html for this is:
<div class="locations">
[wpv-control field="location-zone" auto_fill="wpcf-location-zone" auto_fill_default="All" type="checkboxes" url_param="location"]
</div>
This still listing out all of my locations with checkboxes and an All checkbox, but only in one column.
