Your question is tagged "Ext4, Ext4.1 and Ext2". Which is it? — Evan Trimboli, Nov 21 '16 at 10:05
it has to work in extjs2.0, if its works here i will migrate the same to extjs4 — Bhaskara Arani, Nov 21 '16 at 10:07

For ExtJS 2, you can do it by applying custom list css class to the listClass ComboBox config and set that class to force an overflow: hidden style like this:

Ext.onReady(function() {
  new Ext.form.ComboBox({
    renderTo: 'comboContainer',

    name:'cmbRating',
    id:'cmbRat',
    store: new Ext.data.SimpleStore({
      fields: ["wordRating","wordRatingValue"],
      data: [["0","XXXX Word XXX XXX XXXXXXXX XXXXX AAAAA"],["1","AAAAA Word"],["2","SSSSS Word"],["3","XXXX Word"],["4","AAAAA Word"],["5","SSSSS Word"],["6","XXXX Word"],["7","AAAAA Word"],["8","SSSSS Word"],["0","XXXX Word"],["1","AAAAA Word"],["2","SSSSS Word"],["3","XXXX Word"],["4","AAAAA Word"],["5","SSSSS Word"],["6","XXXX Word"],["7","AAAAA Word"],["8","SSSSS Word 1"]]
    }),
    displayField:'wordRatingValue',
    valueField:"wordRating",
    mode: 'local',
    triggerAction: 'all',
    forceSelection: true,
    editable: false,
    allowBlank: false,
    blankText: 'Plase choose a rating.',
    fieldLabel: '*Rating',
    anchor: '90%',
    listClass: 'x-combo-hide-scrollbars'
  });
});

.x-combo-hide-scrollbars .x-combo-list-inner {
  overflow: hidden !important;
}

<link rel="stylesheet" type="text/css" href="http://zikro.gr/dbg/html/extjs/extjs-2.2.1/css/ext-all.css" />
<script type="text/javascript" src="http://zikro.gr/dbg/html/extjs/extjs-2.2.1/adapter/ext/ext-base.js""> </script>
<script type="text/javascript" src="http://zikro.gr/dbg/html/extjs/extjs-2.2.1/ext-all.js""> </script>
<div id="comboContainer"></div>

For ExtJS 4, there is the autoScroll parameter that allows to enable or disable the scrollbars if we apply it to the listConfig parameters:

Ext.onReady(function() {
  new Ext.form.ComboBox({
    renderTo: 'comboContainer',

    name:'cmbRating',
    id:'cmbRat',
    store: new Ext.data.SimpleStore({
      fields: ["wordRating","wordRatingValue"],
      data: [["0","XXXX Word XXX XXX XXXXXXXX XXXXX AAAAA"],["1","AAAAA Word"],["2","SSSSS Word"],["3","XXXX Word"],["4","AAAAA Word"],["5","SSSSS Word"],["6","XXXX Word"],["7","AAAAA Word"],["8","SSSSS Word"],["0","XXXX Word"],["1","AAAAA Word"],["2","SSSSS Word"],["3","XXXX Word"],["4","AAAAA Word"],["5","SSSSS Word"],["6","XXXX Word"],["7","AAAAA Word"],["8","SSSSS Word"]]
    }),
    displayField:'wordRatingValue',
    valueField:"wordRating",
    mode: 'local',
    triggerAction: 'all',
    forceSelection: true,
    editable: false,
    allowBlank: false,
    blankText: 'Plase choose a rating.',
    fieldLabel: '*Rating',
    anchor: '90%',
    listConfig: {
      autoScroll: false
    }
  });
});

<div id="comboContainer"></div>
