Extends SilverStripes GroupedDropdownField to add the Select2 UI
The AjaxSelect2Field is a dropdown field that makes use of the ajax result loading and infinite scroll features of select2. This is really useful when you need to offer users a way of choosing an object from a list of hundreds or thousands of records that would either break or make standard dropdown/select fields slow and heavy to load. Note that this does not currently work with multiple selection. PR welcome ;)
A basic implementation will use configuration defaults to provide a dropdown list of SiteTree objects, suitable for searching for and selecting a page.
$field = AjaxSelect2Field::create('PageID');
You can configure your instance of AjaxSelect2Field with the following api. The setConfig() method is chainable, too.
// Set a class to search for. Defaults to SiteTree $field->setConfig('classToSearch', 'MyCustomObject'); // Set a list of fields to search on. Default is Title $field->setConfig('searchFields', array('Title', 'ID')); // Limit the number of results loaded per page (scroll set). Default is 200 $field->setConfig('resultsLimit', 100); // The number of characters typed before search results are displayed. Default is 2. $field->setConfig('minimumInputLength', 3); // Configure how items should be displayed in the results list. The value gets parsed by the template parser // You can use HTML too. Default is '$Title'. $field->setConfig('resultsFormat', '<strong>$Title</strong><br />$AbsuluteLink'); // Configure how the currently selected item should be displayed. Default is '$Title'. $field->setConfig('selectionFormat', '$Title ($ClassName)'); // Configure the text displayed when no item is selected. Default is 'Search...' $field->setConfig('placeholder', 'Search for a Page...'); // Allow selection of multiple results. NOTE - you must handle the selected IDs (comma separated list) in code $field->setConfig('multiple', true);
