DHTMLXComboBox attaching to DHTMLX Message Modal Box problem

I have been using DHTMLX Message Library from https://github.com/DHTMLX/message/
I love it! But i have been trying to attach DHTMLX ComboBox to it and have been having problem with the dropdown functionality not working.

[code]

Country

box1 = dhtmlx.modalbox({
title:“Submit”,
content: “submitbox”
});

dhtmlx.modalbox(box1);
dhxComboCountry = new dhtmlXCombo(“subcountry”,“alfa3”,275);
dhxComboCountry.loadXML(“php/getcountry.php”);
[/code]

Once attached, the dropdown menu of the combobox does not work.
Is there a work around to this issue?
Will appreciate your help.

Thanks.

We need completed demo to reproduce your issue:
docs.dhtmlx.com/doku.php?id=othe … leted_demo

Have created a demo …

Please click “SELECT” button to see the box.

A standard select box works fine.
However, the combo box dropdown seems to be created in the back of the dhtmlx modal box window.
How can i solve this?

Many Thanks

It is z-index issue. Combo drop down has 12000, and your “demo box” object - 20000.
You need apply in the tag the next CSS rules:

.dhx_combo_list { z-index: 30000}
