I need a user to select an option so when submit is clicked...

Customers must select an order option for richselect ordertype, so when submit is clicked, how can I ensure the value:“Which Pizza Do You Want?” does not validate as an order, while the other options are valid selections…

webix.ui({
	  container:"areaA",
		view:"form",
		id:"orderform",
		width:450,
		margin:0,
		padding:0,
    	scroll:false,
		borderless:true,				
		elements:[{
		  view:"tabview",
			tabbar:{ options:["Contact Info","Order Info"]}, animate:false,
			cells:[
							{ id:"Contact Info", rows:[
								{ rows:[ 
									{ view:"text", name:"name", label:"Name", value:"", labelWidth:155},
									{ view:"text", name:"address", label:"Address", value:"", labelWidth:155 },
									{ view:"text", name:"phonenum", label:"Phone Number", value:"", labelWidth:155 }
								]}
							]},
							{ id:"Order Info", visibleBatch:"Credit Card", rows:[
		                        { view:"richselect", name:"ordertype", label:"Pizza Order", labelWidth:155, value:"Which Pizza Do You Want?", options:["Pizza + Single Topping","Pizza + Two Toppings","Pizza + Three Toppings","Pizza Dinner Package"]},
		                        { view:"radio",  name:"payment", label:"Payment By" , labelWidth:155, value:"Credit Card", options:["Credit Card","Paypal"], click:function(){
		                            $$("Order Info").showBatch(this.getValue());}
		                        },
								{ view:"text", batch:"Credit Card", name:"ccname", label:"Credit Card Name", labelWidth:155},
								{ view:"text", batch:"Credit Card", name:"ccnumber", label:"Credit Card Number", labelWidth:155},
								{ view:"text", batch:"Credit Card", name:"ccexpire", label:"Expiration Date", labelWidth:155},
								{ view:"text", batch:"Paypal", name:"pp", label:"Paypal Email", labelWidth:155}
							]}
						]
					},
					{ 
						view:"form", width:200, scroll:false,
						cols:[
							{ view:"button", label:"Submit", height:30, width:100, click:function(){				
								if ($$('orderform').validate()) {
									webix.alert("ORDER HAS BEEN PLACED.");
								}
								else
									webix.alert({ type:"error", text:"INFORMATION MISSING." });
								}}
						]
					}
				],
				rules:{
					name: webix.rules.isEmail,
					phonenum: webix.rules.isNotEmpty,
					address: webix.rules.isNotEmpty,
					ccname: webix.rules.isNotEmpty,
					ccnumber: webix.rules.isNotEmpty,
					ccexpire: webix.rules.isNotEmpty,
					pp: webix.rules.isEmail
				}			
			});

You can use a custom function as validation rule

rules:{
    ordertype:function(value){ return value != "Which Pizza Do You Want?" }
}

How can I highlight the richselect box reddish similar to the input boxes that result invalid?

Okay… got it working

It must work by default in Webix 1.9
