I'm not too sure what you mean without some code of what you want to do, but I think you mean that you want to do something to the first item in a handlebars loop? If its that let me try and give it a shot:

This is a little tricky as the version of handlebars shipped with meteor does not yet do this so you need to do it manually.

Use index values in the transform

Template.hello.items = function() {
    var i = 0;
    return Items.find({}, { transform: function(doc) {
        i++;
        if(i==1) doc.first = true;
        return doc;
    }});
}

So this adds a virtual first field in your document if its the first one

Your html loop

{{#each items}}
    {{#if first}}
        This is the first item
    {{/if}}
    ....
{{/each}}
