How to display only the second level menu for the desired section?

Question

MODX

There are sections, each with subsections.
It is necessary in each section to display the menu only from its (related only to this section) subsections.
This code outputs only for one section, and I need for each.

menuRow Template

<li ><a href="" title="" ><span></span></a>
<div class="it" style="display: none">
<a href="#">Потолок на кухне</a><br/>
<a href="#">Потолок в ванной</a><br/>
<a href="#">Каталог цветов</a>
</div>
    <div class="prew">
        <div class="img-prew" style="display:none">
            <img src="" width="120" height="120" ><br/>
            <a class="link-left-menu" href="" title=""></a>
        </div>
    </div>
</li>

Please respond. Thanks in advance.

Answer 2

I looked at your code and did not understand what it should do in the end. Describe the desired result. From what I've seen, everything works.
