  • IE6 (6.0.2900) on WinXP
DOCTYPE tested against:
  • <!DOCTYPE html>
  • <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

  • The dropdown list only shows the first item after clicking the trigger the first time. The other items remain hidden. When you click again on the trigger, all items are visible. This problem occurs in IE6 only. The screen shots says it all (reproduce, what expected and what not.)
Test Case:
Ext.define('MyApp.view.TestForm', {
    extend: 'Ext.form.Panel',
    initComponent: function() {
        var me = this;

        Ext.applyIf(me, {
            items: [
                    xtype: 'combobox',
                    name: 'id_country',
                    fieldLabel: 'Land',
                    displayField: 'description',
                    store: 'Countries',
                    valueField: 'id_country'
