free-jggrid treeGrid expands at bottom of the table
<p>I want to use a treeGrid for eBay categories.</p>

<p>All categories started collapsed (pic: <a href="http://i.stack.imgur.com/DxeHt.png" rel="nofollow">collapsed categories</a>)</p>

<p>After klicking on <strong>Stamps</strong> the subcategories expands at the bottom of the table and not below <strong>Stamps</strong> (pic: <a href="http://i.stack.imgur.com/LVVAP.png" rel="nofollow">expanded category Stamps</a>)</p>

<p>My table definition:</p>

<pre><code>$('#list').jqGrid({
cmTemplate:{sortable:false, autoResizable: true},
multiSort: false,
url:'/admin/ebay/kategorien/get_jqgrid',
datatype:'json',
mtype:'POST',
jsonReader:{ repeatitems: false },
colModel:[{name:'id',index:'id',width:1,hidden:true,key:true},
          {name:'name', label:'Name', width:200},
          {name:'site_id', label:'Site', width:60},
          {name:'cat_id', label:'Kat.-ID', width:60},
          {name:'leaf_category', label:'Erlaubt', width:60},
          {name:'in_use', label:'Benutzen', width:64,
           formatter:'checkbox', align:'center', stype:'select',
           editoptions:{value:':Alle;-:-;+:+'}}],
pager:'#pager', 
height:'auto',
autowidth:false,
shrinkToFit:false,
guiStyle: 'bootstrap',
viewrecords:true,
gridview:true,
loadComplete: function () {
$(this).triggerHandler('resize.jqGrid');
},
editurl:'/admin/ebay/kategorien/edit',
iconSet:'fontAwesome',
treeGrid:true,
treeGridModel:'adjacency',
ExpandColumn:'name',
ExpandColClick:'true',
caption:'eBay-Kategorien'
});
</code></pre>

<p>Data example:</p>

<pre><code>{
 "site_id":"0",
 "cat_version":"114",
 "cat_id":"20081",
 "cat_level":"1",
 "name":"Antiques",
