I think you're looking for a kind (simplified working example.)
Ext.create('Ext.form.ComboBox', { fieldLabel: 'Choose State', store: states, typeAhead: true, // this will simply show the typed text if nothing is found. queryMode: 'local', displayField: 'name', valueField: 'abbr', tpl: Ext.create('Ext.XTemplate', '<tpl for=".">', '<div class="x-boundlist-item">{abbr}</div>', '</tpl>' ), displayTpl: Ext.create('Ext.XTemplate', '<tpl for=".">', '<tpl if="name.length == 0"> ', 'no data', // You can return any other additional value or formating here '<tpl else>', '{name}', // You can return any other additional value or formating here '</tpl>', '</tpl>' ), valueNotFoundText: 'no data' // this will be displayed if no record is found after setValue() });
JSFiddle works here
So how does it work
Just set the template for the drop-down menu (if necessary at all in your case) and set the template for the display field.
Both examples are simplified because I donβt know your whole template.
Updated examples
Note. I would not use type as a property name, because it is a kind of reserved name, because it identifies the type of field / primitive
var states = Ext.create('Ext.data.Store', { fields: ['abbr', 'name','ctype'], data : [ {"abbr":"AL", "name":"Alabama", "ctype":"AL"}, {"abbr":"AK", "name":"Alaska", "ctype":"AK"}, {"abbr":"AZ", "name":"Arizona", "ctype":""} ] }); // Create the combo box, attached to the states data store Ext.create('Ext.form.ComboBox', { fieldLabel: 'Choose State', store: states, typeAhead: true, // this will simply show the typed text if nothing is found. queryMode: 'local', displayField: 'name', valueField: 'abbr', tpl: Ext.create('Ext.XTemplate', '<tpl for=".">', '<tpl if="ctype.length == 0"> ', '<div class="x-boundlist-item">{name}<p><font size="1">no data</font></p></div>', '<tpl else>', '<div class="x-boundlist-item">{name}{ctype}<p><font size="1">{ctype}</font></p></div>', '</tpl>', '</tpl>' ), displayTpl: Ext.create('Ext.XTemplate', '<tpl for=".">', '<tpl if="itype.length == 0"> ', 'no data', '<tpl else>', '{name}', '</tpl>', '</tpl>' ), valueNotFoundText: 'no data', // this will be displayed if no record is found after setValue() renderTo: Ext.getBody() });
