Hi..
I'm using  JSON binding to the following -   a fact contains  a name    so   fact.name = 'ABC',  fact.name ='XYZ'

  <ion-list>
     <ion-item ng-repeat="fact in facts" item="fact" >

     if fact contains  ABC I want to show the item like this.

       use ABC class and show it in BOLD

    if fact contains   XYZ  I want to show the itme like this.

    use XYZ class and show in RED


        and so on



How do I conditionally show / format etc an item based on the value?

You can just create CSS classes that match those names and apply them with ng-class.
Can actually be even with the normal class like:
<ion-item ng-repeat="fact in facts" item="fact" class="{{fact.name}}">

How do I check if fact.name = 'XYZ' to use a particular class, say class = "RED".

How do I structure the item

like this?

 <ion-item class="RED">

thanks

Can't you create a class called XYZ like:
.XYZ{
color: #f00;
}

Open in new window

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

You can even prefix it to avoid conflicts:
<ion-item ng-repeat="fact in facts" item="fact" class="fact_{{fact.name}}">

Open in new window

And create a class like:
.fact_XYZ{
color: #f00;
}

Open in new window

How do I check if the fact.name is 'XYZ' ?   I can't name the class XYZ... it will not match the value in fact.name.

the class for XYZ maybe  Called 'Special_Class_For_XYZ'

That's my point.
To make it easier to maintain it should have the same name, otherwise you have to create a function in the controller that does the mapping:
$scope.getFactClass = function(fact){
    var name = fact.name;
    
    switch{
        case 'XYZ':
            return 'Special_Class_For_XYZ';
        case 'ABC':
            return 'SomeOtherClassForABC';
        default:
            return '';
        
    }
}

Open in new window

and use it like:
<ion-item ng-repeat="fact in facts" item="fact" class="{{getFactClass(fact)}}">
