How to nest options with <xen:controlunit>?

[tyteen4a03]

Basically I want to achieve this:


(notice that the checkbox next to the option are gone)
I tried using <xen:controlunit> and multiple <xen:things> but they wouldn't stack properly, using <dt> and <ul> for nesting but it looks weird, I'll upload a pic if anybody needs it). Is there a way I can build nested options with <xen:controlunit>?

I ended up solving this problem by reinventing the wheel... *sigh*

boldText class is just font-weight: bold.

<xen:require css="3ps_usergroup_ranks_admin.css" />
 
<dl class="ctrlUnit">
    <input type="hidden" name="{$listedFieldName}" value="{$preparedOption.option_id}" />
    {xen:raw $editLink}
    <dt>{$preparedOption.title}</dt>
    <dd>
        <ul>
            <li>
                <label class="boldText">{xen:phrase 3ps_usergroup_ranks_in_posts}:</label>
                <ul>
                    <li>
                        <label for="{$fieldPrefix}[{$preparedOption.option_id}][style][posts]">{xen:phrase 3ps_usergroup_ranks_calculation_style}</label>
                        <xen:radio name="{$fieldPrefix}[{$preparedOption.option_id}][style][posts]" selected="{$preparedOption.option_value.style.posts}">
                            <xen:option value="0">{xen:phrase 3ps_usergroup_ranks_fixed}</xen:option>
                            <xen:option value="1">{xen:phrase 3ps_usergroup_ranks_dynamic}</xen:option>
