Howdo I select from a tree in a telerik drop down?

I have a telerik Tree View in a Telerik Dropdown. How do I get Katalon to select an item from the tree in the dropdown?

example:

<div class=“rcbSlide” style=“z-index:6000;”>
<div id=“cboOrganizationContainer_DropDown” class="RadComboBoxDropDown RadComboBoxDropDown_Windows7 " style=“display:none;”>
<div class=“rcbScroll rcbWidth” style=“width:100%;”>
<ul class=“rcbList” style=“list-style:none;margin:0;padding:0;zoom:1;”>
<li class=“rcbItem rcbTemplate”>
<div id=“div1”>
<div id=“cboOrganizationContainer_i0_rtvOrganization” class=“RadTreeView RadTreeView_Windows7” style=“overflow:auto;height:250px;width:100%;”>
<ul class=“rtUL rtLines”>
<li class=“rtLI rtFirst rtLast”>
<div class=“rtTop”>
<span class=“rtSp”></span>
<span class=“rtMinus”></span>
<span class=“rtIn”>Parent</span>
</div>
<ul class=“rtUL”>
<li class=“rtLI rtLast”>
<div class=“rtBot”>
<span class=“rtSp”></span>
<span class=“rtMinus”></span>
<span class=“rtIn”>Child1</span>
</div>
<ul class=“rtUL”>
<li class=“rtLI rtLast”>
<div class=“rtBot”>
<span class=“rtSp”></span>
<span class=“rtMinus”></span>
<span class=“rtIn”>Child 1-1</span>
</div>
<ul class=“rtUL”>
<li class=“rtLI rtLast”>
<div class=“rtBot”>
<span class=“rtSp”></span>
<span class=“rtMinus”></span>
<span class=“rtIn”>Child 1-1-1</span>
</div>
<ul class=“rtUL”>
<li class=“rtLI”>
<div class=“rtTop rtDisabled”>
<span class=“rtSp”></span>
<span class=“rtMinus”></span>
<span class=“rtIn”>Child 1-1-1-1</span>
</div>
</li>
</ul>

Hi Don,

Katalon Studio has a wide range of keywords here to deal with dropdowns (combo boxes) such as your case.

You should try them out to see if they fit your needs.
