Form with Combo in a window

when i have got a window wich includes a form with combo multiselect, the list options of the combo appears behind the window. The form is attached to the window with the attach method.

Unfortunately, your issue cannot be reconstructed locally.
The following snippet works well for me locally:
Please, try to update your dhx.Suite build.
If the problem still occurs for you please, provide a complete demo or a demo link, where the problem could be reconstructed.

Maybe, you could try the filter method during the combo definition:

  type: "combo",
  name: "foo",
  label: "Foo",
  filter: function (item, target) {
    return true;
