ColumnedList

An SS_ListDecorator to facilitate stacking data vertically in columns. Supports left and right “weighting”.

Example:

use Kinglozzer\SilverStripeColumnedList\ColumnedList;
use SilverStripe\CMS\Model\SiteTree;

class Page extends SiteTree
{
    public function ColumnData()
    {
        return ColumnedList::create($this->SomeDataList());
    }
}

<% loop ColumnData.Stacked(3) %>
    <div style="float: left">
        <h3>Column {$Pos}</h3>
        <ul>
            <% loop Children %>
                <li>Item {$Pos}</li>
            <% end_loop %>
        </ul>
    </div>
<% end_loop %>

Assuming SomeDataList() contains 5 items, the output would be:

Column 1	Column 2	Column 3
Item 1	Item 3	Item 5
Item 2	Item 4	.

“Right-heavy” stacking:

Using the same above example:

<% loop ColumnData.Stacked(3, 'Children', 0) %>
    <div style="float: left">
        <h3>Column {$Pos}</h3>
        <ul>
            <% loop Children %>
                <li>Item {$Pos}</li>
            <% end_loop %>
        </ul>
    </div>
<% end_loop %>

Assuming SomeDataList() contains 5 items, the output would be:

Column 1	Column 2	Column 3
Item 1	Item 2	Item 4
.	Item 3	Item 5
