## Usage ## Usage
To enable sorting on a has_many relationship set up an integer field on your data object. Also for has_many relationships make sure to set the $default_sort on the dataobject to this new integer 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 below for an example. For new DataObjects you do not need to increment the Sort order yourself in your DataObject GridFieldSortableRows will automatically do this the next time the grid is displayed.
