title: Remove Columnmenu.columns from kendo ui grid
body: <p>i'm working with KENDO UI Grid today, i need in a grid that in the columnmenu there are active the item "sort ascending, sort descending, columns, filter", but i need also that "columns" item disappear in the other columns, so that ppl can only hide from the first column.
  For example, 
  in this code</p>
  
  <pre><code>&lt;div id="grid"&gt;&lt;/div&gt;
  &lt;script&gt;
  $("#grid").kendoGrid({
      columnMenu:true,
      filterable: true,
      sortable: true,
      columns: [
          { field: "productName" },
          { field: "category" }
      ],
      dataSource: [
         { productName: "Tea", category: "Beverages" },
          { productName: "Coffee", category: "Beverages" },
          { productName: "Ham", category: "Food" },
          { productName: "Bread", category: "Food" }
      ]
  });
  &lt;/script&gt;
  </code></pre>
  
  <p>the result would be that in every column i'll get a menù with 4 item:</p>
  
  <ol>
  <li>sort ascending</li>
  <li>sort descending</li>
  <li>columns</li>
  <li>filter</li>
  </ol>
  
  <p>now i need that only for "productName" column there are all 4 voices, and for "category" column (and for every other possible column), menu voice contain only:</p>
  
  <ol>
  <li>sort ascending</li>
  <li>sort descending</li>
  <li>filter</li>
  </ol>
  
  <p>is that possible?</p>
  
  <p>ty for any advice</p>
