Build dynamic sub menu from JSON data using JQuery?

I want to build sub menu for menu item from json data.

Menu

  <div class="subnav-fixed" id="menuContrainer" runat="server">
        <ul class="nav nav-pills">
           <li id="Li0"><a href="Default.aspx">Home </li>
           <li id="Li1"><a href="InitiativeGrid.aspx">Initiative</a></li>
           <li id="Li2"><a href="Reports.aspx">Reports</a></li>
           <li id="Li3"><a href="EditInitiative.aspx">Edit Initiatives</a></li>            
        </ul>
    </div>

JSON

data =
    "{"d":[
        {"__type":"Tableau_Reports:#CostReductionData",
            "ClientIdx":1,
            "GroupName":"HR",
            "ReportGroup":"1",
            "ReportHeight":"800",
            "ReportName":"Baseline Vs Active Employees",
            "ReportOrder":"0",
            "ReportUrl":"https://company.com/t/sga/views/HRReports/BaselineandActiveEmployees"
        },
        {"__type":"Tableau_Reports:#CostReductionData",
            "ClientIdx":1,
            "GroupName":"HR",
            "ReportGroup":"1",
            "ReportHeight":"800",
            "ReportName":"Level vs Direct Reports",
            "ReportOrder":"0",
            "ReportUrl":"https://company.com/t/sga/views/HRReports/LevelvsDirectReports"
        },
        {"__type":"Tableau_Reports:#Alixpartners.SGACostReductionData",
            "ClientIdx":1,
            "GroupName":"Finance",
            "ReportGroup":"2",
            "ReportHeight":"800",
            "ReportName":"Spans and Layers",
            "ReportOrder":"0",
            "ReportUrl":"https://company.com/t/sga/views/HRReports/SpansandControl"
        }]
    }"

I want to display sub menu for Report menu Item like this

Home Initiative Reports Edit Initiative
                  |
                  HR- Baseline Vs Active Employees
                    - Level vs Direct Reports
                  |
                  Finance - Spans and Layers

How can we do this with Jquery?

try this logic

var html='<ul>';

$.each(data.d, function(i, item) {
    //alert(item.GroupName);
    html+='<li><a>'+item.GroupName+'</a></li>'
});

html+='</ul>';

I'm not sure how you're getting your data, but using jquery to add HTML is phenomenally easy. Base example, you are using $.ajax() to get your data. With your given HTML, and JSON data return, you might do something like:

$(function() {
    $.ajax({
        url: "http://www.yourDomain.com/yourController/yourMethod",
        dataType: "json",
        type: "get",
        beforeSend: function(xhr, settings) {
            $("#Li2").find("ul").remove();
        },
        success: function(data, status, xhr) {
            if (data["d"]) {
                if (data["d"].length) {
                    var items = data["d"],
                        ul = $("<ul />").appendTo($("#Li2"));
                    for (x in items) {
                        var li = $("<li />").appendTo(ul);
                        li.append($("<a />", { href: items[x].ReportUrl, text: items[x].ReportName }));
                    }
                }
            }
        }
    })
})

OR if the JSON is a variable in your JS then you would just use $.each() with same type setup:

$(function() {
    var $ul = $("<ul />").appendTo($("#Li2"));
    $.each(data.d, function(index, item) {
        var li = $("<li />").appendTo($ul);
        li.append($("<a />", { href: item.ReportUrl, text: item.ReportName }));
    })
})

And just for thoroughness, a combo of the 2:

$(function() {
    $.ajax({
        url: "http://www.yourDomain.com/yourController/yourMethod",
        dataType: "json",
        type: "get",
        beforeSend: function(xhr, settings) {
            $("#Li2").find("ul").remove();
        },
        success: function(data, status, xhr) {
            if (data["d"]) {
                if (data["d"].length) {
                    var ul = $("<ul />").appendTo($("#Li2"));
                    $.each(data.d, function(index, item) {
                        var li = $("<li />").appendTo(ul);
                        li.append($("<a />", { href: items[x].ReportUrl, text: items[x].ReportName }));
                    });
                }
            }
        }
    })
})
