I need to insert a <ul> tag inside an specific class with childs. Tried with jquery selectors without success :(

I have this one

            <ul id="reportsTree" class="tree">
              <li class="reportGroupItem">Coffee</li>
              <li class="reportGroupItem">Tea
                    <li class="reportItem">Black tea</li>
                    <li class="reportItem">Green tea</li>
              </li>
              <li class="reportGroupItem">Milk</li>
        </ul>

But I need this one

            <ul id="reportsTree" class="tree">
            <li class="reportGroupItem">Coffee</li>
            <li class="reportGroupItem">Tea
                <ul>
                    <li class="reportItem">Black tea</li>
                    <li class="reportItem">Green tea</li>
                </ul>
            </li>
            <li class="reportGroupItem">Milk</li>
        </ul>

Look that the two <li_> elements with the class "reportItem" are wrapped by a element... but I cannot just wrap "reportItem" elements with because can be more than one (like the example) and I cannot just insert the element after a "reportGroupItem" becasue maybe there are no childs inside... So, what can I do.

I've tried with .wrapInner(), .wrapAll, looking for first child...

Very easy, but very frustrating for me :(

Malformed code is generated like this:

                <logic:iterate name="ReportGenerationForm" property="reportGroups" id="group">
                <li class="reportGroupItem">
                    <bean:write name="group" property="code" /> 
                    <logic:iterate name="group" property="reports" id="report" indexId="index">
                        <li class="reportItem">
                            <bean:write name="report" property="code" />
                        </li>
                    </logic:iterate>
                </li>
            </logic:iterate>

Reframing the question based on OPs comment "this was my first try", by changing the source to output as:

<logic:iterate name="group" property="reports" id="report" indexId="index">
  <ul>
    <li class="reportItem">
      <bean:write name="report" property="code" />
    </li>
  </ul>
</logic:iterate>

which will output as:

<ul id="reportsTree" class="tree">
  <li class="reportGroupItem">Coffee</li>
  <li class="reportGroupItem">Tea
    <ul>
      <li class="reportItem">Black tea</li>
    </ul>
    <ul>
      <li class="reportItem">Green tea</li>
    </ul>
  </li>
  <li class="reportGroupItem">Milk</li>
</ul>

We can then, based on this answer combine the lis inside the inner uls using:

  $("ul > li > ul + ul").each((i, e) => {
    $(e).children('li').appendTo($(e).prev());
    $(e).remove();
  })

you could use ids/classes instead, eg ul#reportsTree > li.reportGroupItem > ul + ul

which says: find all lists that follow another list inside a list item inside a list. The key part is the ul + ul. Similar would be ul>li>ul:not(:first)

Then moves all the children list items to the previous ul (no need for .prev("ul") or similar as the ul+ul already confirms previous is a ul)

Updated snippet below. Here, I've given each ul and underline/separator so you can visibly see them combine when clicking the button. Or you can inspect element to see the effect (and that there's no "orphaned"(childless) ul left behind)

$("button").on("click", () => {
  $("ul>li>ul+ul").each((i, e) => {
    //console.log($(e).text())
    $(e).children('li').appendTo($(e).prev());
    $(e).remove();
  })
});

ul {
  border-bottom: 1px solid #CCC
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul id="reportsTree" class="tree">
  <li class="reportGroupItem">Coffee</li>
  <li class="reportGroupItem">Tea
    <ul>
      <li class="reportItem">Black tea</li>
    </ul>
    <ul>
      <li class="reportItem">Green tea</li>
    </ul>
  </li>
  <li class="reportGroupItem">Milk</li>
</ul>
<button>
click me
</button>
