group items accourding to invoice ID

Question

I need to prepare invoice lists and in the each invoice there are more items added by user while shopping here my model

public partial class tblNormalSatisBekleyen
{
    public int Id { get; set; }
    public string urunAdi { get; set; }
    public string QB { get; set; }
    public int miktar { get; set; }
    public string  cari { get; set; }
    public int  plasiyerId { get; set; }
    public string paraBirimi { get; set; }
    public int  KDV { get; set; }
    public string satisTuru { get; set; }
    public string siparisId { get; set; }

    public virtual tblCariGenel tblCariGenel { get; set; }
}

my controller is like that

HomeController.cs

var orderList = db.tblNormalSatisBekleyen.OrderByDescending(x => x.tarih);
return View(orderList);

and my view page is like that

<table id="example" class="table table-bordered table-striped">
<thead>
    <tr>
        <th>Id</th>
        <th>Cari</th>
        <th>Sipariş Turu</th>
        <th>Detay</th>
    </tr>
</thead>
<tbody>
    @foreach (var item in Model)
    {
        <tr>
            <td>@item.Id</td>
            <td>@item.cari</td>
            <td>@item.satisTuru</td>
            <td><a href="/Home/Details">Details</a></td>
        </tr>
    }
</tbody>

but when I run this all items are displayed I just want to show just invoice title and group by "SiparisId" than after click the button show all the ordered items in the tables
