Vertical Navbar in Bootstrap 3 using UiBinder

[kellelein]

I have a Navbar in my project (GWT, GWTBootstrap3, UiBinder), I would like to make vertical in UiBinder.

In HTML it is quite simple

<div class = "nav nav-pills nav-stacked col-sm-3"> 
    <li> <a> Home </a> </li> 
    <li> <a> Settings</a> </li> 
</div> 

But it must be possible to do the same in UiBinder. As far as I understand it is only possible to set the position of the Navbar to FIXED_TOP, FIXED_BOTTON and one more.

My code looks like this

<g:HTMLPanel>
        <g:ScrollPanel>
            <b:Container >
                 <b:Navbar position="FIXED_TOP">
                    <b:Container>
                        <b:NavbarHeader>
                            <b:NavbarBrand targetHistoryToken="{nameTokens.getHome}" ui:field="brand" text="{resources.ProductName}" />
                            <b:NavbarCollapseButton dataTarget="#navbar-collapse" />
                        </b:NavbarHeader>

                        <b:NavbarCollapse b:id="navbar-collapse">
                            <b:NavbarNav>

                                <b:ListDropDown ui:field="admindropdown">
                                    <b:AnchorButton dataToggle="DROPDOWN" text="{resources.CardHolder}" />
                                    <b:DropDownMenu>
                                        <b:AnchorListItem text="{resources.Employee}" targetHistoryToken="{nameTokens.getCardholderlist}" />
                                        <b:AnchorListItem text="{resources.Guest}" targetHistoryToken="{nameTokens.getHome}" />
                                        <b:AnchorListItem text="{resources.Vendor}" targetHistoryToken="{nameTokens.getHome}" />
                                    </b:DropDownMenu>
                                </b:ListDropDown>

                                <b:ListDropDown>
                                    <b:AnchorButton dataToggle="DROPDOWN" text="{resources.User}" />
                                    <b:DropDownMenu>
                                        <b:AnchorListItem text="{resources.Customer}" targetHistoryToken="{nameTokens.getHome}" />
                                        <b:AnchorListItem text="{resources.Technician}" targetHistoryToken="{nameTokens.getHome}" />
                                        <b:AnchorListItem text="{resources.Portal}" targetHistoryToken="{nameTokens.getHome}" />
                                        <b:AnchorListItem text="{resources.Cloud}" targetHistoryToken="{nameTokens.getHome}" />
                                    </b:DropDownMenu>
                                </b:ListDropDown>

                                <b:ListDropDown>
                                    <b:AnchorButton dataToggle="DROPDOWN" text="{resources.Configuration}" />
                                    <b:DropDownMenu>
                                        <b:AnchorListItem text="{resources.Customer}" targetHistoryToken="{nameTokens.getCustomerlist}" />
                                        <b:AnchorListItem text="{resources.Company}" targetHistoryToken="{nameTokens.getCompanylist}" />
