Answer 1

I don't know about htmlhelper, but the linq groupby method is simple to use:

var firstnamegroups = items.GroupBy(item => item.FirstName);

Answer 2

I'll help you with the query only, you can continue after this point with the your HTML code.

Sample Data:

List<Person> list = new List<Person>();
list.Add(new Person() { FirstName = "A", ID = 1 });
list.Add(new Person() { FirstName = "B", ID = 2 });
list.Add(new Person() { FirstName = "B", ID = 3 });
list.Add(new Person() { FirstName = "C", ID = 4 });

The LINQ expression:

var result = list.GroupBy(item => item.FirstName);

Put here your HTML code:

foreach (var item in result)
{
    string name = item.Key;
    // Add here the div and use [name]

    foreach (var person in item)
        ;// Add here the items in the div
}

Good luck!
