yii\jui\Selectable::begin PHP Method

begin() public static method

This method creates an instance of the calling class setting the MODE_BEGIN mode. Any item between Selectable::begin and [[end()]] which match the filter attribute, will be selectable. It will apply the configuration to the created instance. A matching [[end()]] call should be called later. As some widgets may use output buffering, the [[end()]] call should be made in the same view to avoid breaking the nesting of output buffers.
