    I am running into a style issue for multi-column combo box with selections. The checkbox and corresponding item are in two lines. (see attached). Here is my code:


    <%@ Page AutoEventWireup="true" CodeFile="DefaultCS.aspx.cs" Inherits="ComboBox.Examples.Functionality.MultiColumnCombo.DefaultCS"
        Language="c#" MasterPageFile="~/MasterPage.master" %>

    <%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>
    <asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">
        <link rel="stylesheet" type="text/css" href="styles.css" />
    <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceholder1" runat="Server">
        <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
                <telerik:AjaxSetting AjaxControlID="Button1">
                        <telerik:AjaxUpdatedControl ControlID="Label1" />

        <div class="demo-container size-narrow">
            <h2>Grid-like multi-column:</h2>
            <telerik:RadComboBox runat="server" ID="RadComboBox1" Height="190px" Width="460px" CheckBoxes="true"
                MarkFirstMatch="true" DataSourceID="SessionDataSource1" EnableLoadOnDemand="true"
                HighlightTemplatedItems="true" OnClientItemsRequested="UpdateItemCountField"
                OnDataBound="RadComboBox1_DataBound" OnItemDataBound="RadComboBox1_ItemDataBound"
                OnItemsRequested="RadComboBox1_ItemsRequested" DropDownCssClass="exampleRadComboBox">
                        <li class="col1">Contact Name</li>
                        <li class="col2">City</li>
                        <li class="col3">Title</li>
                        <li class="col1">
                            <%# DataBinder.Eval(Container.DataItem, "ContactName") %></li>
                        <li class="col2">
                            <%# DataBinder.Eval(Container.DataItem, "City") %></li>
                        <li class="col3">
                            <%# DataBinder.Eval(Container.DataItem, "ContactTitle") %></li>
                    A total of
    <asp:Literal runat="server" ID="RadComboItemsCount" />
            <br />
            <br />
            <h2>Multiple rows and columns:</h2>
            <telerik:RadComboBox ID="RadComboBox2" runat="server" Height="190px" Width="460px"
                DropDownCssClass="multipleRowsColumns" DropDownWidth="460px" />

            <telerik:RadButton runat="server" ID="Button1" Text="Select" OnClick="Button1_Click"></telerik:RadButton>
            <asp:Label runat="server" ID="Label1" />

        <asp:SqlDataSource ID="SessionDataSource1" runat="server"
            ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString35 %>"
            SelectCommand="SELECT * FROM [Customers]"></asp:SqlDataSource>

        <telerik:RadScriptBlock runat="server">
            <script type="text/javascript">
                function UpdateItemCountField(sender, args) {
                    //Set the footer text.
                    sender.get_dropDownElement().lastChild.innerHTML = "A total of " + sender.get_items().get_count() + " items";

    Your help will be greatly appreciated.

    Hello Bin,

    Please add the following styles to your CSS file:
    html .rcbHeader ul,
    html .rcbFooter ul,
    html .rcbItem ul,
    html .rcbHovered ul {
        margin: 0;
        padding: 0;
        width: 90%;
        display: inline-block;
        list-style-type: none;
    html div.RadComboBoxDropDown .rcbItem > label,
    html div.RadComboBoxDropDown .rcbHovered > label {
        display: inline-block;
