We are using the combo box drop down:

                <telerik:RadComboBox ID="rcbAccounts" runat="server" Width="360" DropDownWidth="810" OffsetX="-200"
                    DataValueField="AcctNumber" DataTextField="DisplayString" AutoPostBack="True"
                    AllowCustomText="True" Filter="Contains" ExpandDelay="0" CollapseDelay="0" MaxHeight="300"
                    OnClientDropDownOpening="OnRcbAccountsOpening" Skin="CustomTelerikSkin" EnableEmbeddedSkins="false"
                    EnableViewState="false" EnableScreenBoundaryDetection="true" >
                    <HeaderTemplate>
                        <ul>
                            <li class="rcbColumn" style="width: 330px">Name</li>
                            <li class="rcbColumn" style="width: 70px">Acct #</li>
                            <li class="rcbColumn" style="width: 90px">Type</li>
                            <li class="rcbColumn" style="width: 150px">Address</li>
                            <li class="rcbColumn" style="width: 110px">City</li>
                        </ul>
                    </HeaderTemplate>
                    <ItemTemplate>
                        <ul>
                            <li class="rcbColumn" style="width: 330px">
                                <%#DataBinder.Eval(Container.DataItem, EC.ACCT_NAME).ToString()%></li>
                            <li class="rcbColumn" style="width: 70px">
                                <%#DataBinder.Eval(Container.DataItem, EC.ACCT_NO).ToString()%></li>
                            <li class="rcbColumn" style="width: 90px">
                                <%#DataBinder.Eval(Container.DataItem, EC.ACCT_TYPE).ToString()%></li>
                            <li class="rcbColumn" style="width: 150px">
                                <%#DataBinder.Eval(Container.DataItem, EC.ACCT_ADDR1).ToString()%></li>
                            <li class="rcbColumn" style="width: 110px">
                                <%#DataBinder.Eval(Container.DataItem, EC.ACCT_CITY).ToString()%></li>
                        </ul>
                    </ItemTemplate>
                </telerik:RadComboBox>

It looks like the attached at runtime.  My question is:  Can we align the dropdown area to be left-aligned with the control?  In some cases, the left part of the data gets cut off by the browser window.
