Usage

To enable sorting on a has_many relationship set up an interger field on your data object. Also for has_many relationships make sure to set the $default_sort on the dataobject to this new interger field to ensure that the sort order is applied when the relationship is requested. For many_many relationships you must add a $many_many_extraFields static to the data object defining the relationship, see the SilverStripe documentation for more information on this. If you are using a many_many relationship you will need to do a custom getter to set the sort order of this relationship for use on the front end see bellow for an example.

:::php
public function getMyManyManyRelationship() {
    return $this->getManyManyComponents('MyManyManyRelationship')->sort('SortColumn');
}

To enable drag and drop sorting on the grid field add the following to your grid field's config Grid Field Config

:::php
$myGridConfig->addComponent(new GridFieldSortableRows('{Column to store sort}'));

To move an item to another page drag the row over the respective page button and release.

@TODO

• Optimize re-ordering of a has_many relationship when sorting on a single page
