I tried to solve the problem a different view. (Non-tree components)
Interestingly, the data grid appears on desktop, tablet and phone but did not.

Code:

<div title="Címrendezés" style="padding:0px">
          <table id="dgML_sort"
            data-options="singleSelect:true,border:false,fit:true,fitColumns:true, scrollbarSize: 0,
            onClickRow: onClickRow,
            onAfterEdit: function(index,row,changes){
               save_address_sort(index,row,changes) }
            ">
          </table>
        </div>

Code:

    <meta name="viewport" content="initial-scale=1.0, maximum-scale=1.0, user-scalable=no">
    <meta name="apple-mobile-web-app-capable" content="yes"/>
