jQuery append() под идентификатором элемента?

Я создаю панель навигации, которая управляется на основе значений, полученных из списка SharePoint. Прямо сейчас я использую <ul> для заголовков столбцов и <li> для содержимого. Я могу заставить правильно отображать заголовки, а также правильно отображать содержимое этого столбца. У меня проблемы с тем, что <li> кажется добавленным к <ul>, что здорово, но он также помещает его внутрь него. У моего <ul> есть рамка вокруг него, и я хочу, чтобы содержимое добавлялось непосредственно под этой границей, но вместо этого он помещает все внутри него.

Вот конкретный блок кода, который я считаю неправильным:

$('#TableElement').hover(function () {
$('[id^=Header]').hover(function () {


    $("#" + this.id).append("<li>" + this.id + "</li>");
});
});

Вот весь мой код:

//Print Headers to Screen. This will drive the core functionalty of the navpart
var siteUrl = '/sites/dev';
ExecuteOrDelayUntilScriptLoaded(retrieveListItems, "sp.js");
theCounter = 0;
var Headers = new Array();
var getCurrentElementId = null;
function retrieveListItems() {
var clientContext = new SP.ClientContext(siteUrl);
var oList = clientContext.get_web().get_lists().getByTitle('myList');
var camlQuery = new SP.CamlQuery();
camlQuery.set_viewXml("<Where><IsNotNull><FieldRef Name='Title' /></IsNotNull></Where>");
this.collListItem = oList.getItems(camlQuery);
clientContext.load(collListItem);
clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded),  Function.createDelegate(this, this.onQueryFailed));
}
function onQuerySucceeded(sender, args) {
var listItemInfo = '';
var listItemEnumerator = collListItem.getEnumerator();
while (listItemEnumerator.moveNext()) {
    var oListItem = listItemEnumerator.get_current();
    theCounter += 1;
    Headers[theCounter - 1] = oListItem.get_item('Title');
}
var HeaderDisplay = _.uniq(Headers);
for (var i = 0; i <= HeaderDisplay.length - 1; i++) {
    $('#TableElement').append("<th id=Header" + i + ">" + HeaderDisplay[i] + "::::::" +   "</th>");
}
}
function onQueryFailed(sender, args) {
alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
}

// You got the headers to print as expected. Right now you need to figure out how to get the current ID
// that the mouse is over. Try looking at another project you did where the mouse goes into the table header
// and the outline expands.


$('#TableElement').hover(function () {
$('[id^=Header]').hover(function () {
  // Come back to this:::::::  var content = $(this).html();


    $("#" + this.id).append("<li>" + this.id + "</li>");
});
});


//This should be the universal onmouseover event that will expose only links
//and values relavent to the selected header.

//$(document).ready(function onPageLoad() {
//    $().SPServices({
//        operation: "GetListItems",
//        async: false,
//        listName: "myList",
//        CAMLQuery: "<Query><Where><IsNotNull><FieldRef Name='Title' /></IsNotNull></Where></Query>",
//        completefunc: function completeFunction(xData, Status) {
//            $(xData.responseXML).SPFilterNode("z:row").each(function () {
//                var Headers = "<th>" + $(this).attr("ows_Title") + "</th>";
//                $("#TableElement").append(Headers);
//            });
//        }
//    });
//});
