### Select box columns in a scheduler

When scheduler has a select-like collections , or unit|timeline view - it possible to load the list of related options from a server. In such case the data loading need to be defined on client side as

    	some_collection=scheduler.serverList("type");

On server side , list of options can be retrieved in few ways

- hardcoded list

    	//	both values and labels need to be provided
    	$scheduler->set_options("type",array("1" => "one", "2"=>"two","3" => "three")); // value => label
    	$scheduler->render_table("events","event_id","start_date,end_date,text,type_id");

- list created on base of different table

    	$options = new OptionsConnector($res);
    	//	there must be two fields selected, one as (value), second as (label)
    	$options->render_table("types","type_id","type_id(value),type_name(label)");
    	$scheduler->set_options("type",$options);

    	$scheduler->render_table("events","event_id","start_date,end_date,text,type_id");
