how to get breadcrumbs path in li html mvc anchor tag

Question

Here is my example:

<ul>
        <li><a href="GrandParent.html">Grand Parent</a>
            <ul>
                <li><a href="Parent.html">Parent</a>
                    <ul>
                        <li><a href="child.html">child</a></li></ul>
                </li>
            </ul>
        </li>
    </ul>

 

every li element has a anchor tag next to it (not shown in the code, please assume that).

Now if a select value "Child" from the above code then i should get the below result "Grand Parent/ Parent / Child" and if i select parent then i should get "Grand Parent / Parent"

So basically the i want to get parent with all its child

Here is my code:

@helper GetTreeView(Abacus_CMS.Models.AbacusModel siteMenu, int parentID)
    {
    var url = new System.Web.Mvc.UrlHelper(Context.Request.RequestContext);
    foreach (var i in siteMenu.AbacusMenuList.Where(a => a.ParentCatagoryId.Equals(parentID)))
    {
            <li>
                @{ var submenu = siteMenu.AbacusMenuList.Where(a => a.ParentCatagoryId.Equals(i.Id)).Count();}
                @if (submenu > 0)
                {

                <li style="margin-left: -6px;">
                    <a href="@url.RouteUrl("GettingStarted", new { catname = HttpUtility.UrlEncode(i.Name.Replace(' ', '-'))})" id="@i.Name.Replace(' ', '-').ToLower()" onclick="GetParents()">
                        <i class="fa fa-chevron-right" aria-hidden="true"style="margin-left: 25px; font-size: 10px;">
                        </i><span class="title" style="margin-left: 0px;">@i.Name</span>
                        <span class="arrow " style="height: 4px;"></span>

                    </a>
                    <ul class="sub-menu">
                        @treeview.GetTreeView(siteMenu, i.Id)
                        @* Recursive  Call for Populate Sub items here*@
                    </ul>
                </li>

                @*<span class="collapse collapsible"> </span>*@
                }
                else
                {
                    <a href="@url.RouteUrl("GettingStarted", new { catname = HttpUtility.UrlEncode(i.Name.Replace(' ', '-')) })" style="margin-left: 30px;" id="@i.Name.Replace(' ', '-').ToLower()">

                            @i.Name
                        </a>
                        }

                        </li>

                }
                }
