    Default combo box - select a value on key press

    Hi,

    I'm looking for a very obvious behavior of HTML select in ExtJs 4 combo box.
    If I press in a key then the control should move to combo box value starting from that key. How can I achieve this.

    I have tried
    Code:
    queryMode:'local'
    which is doing same kind of thing but its allowing editing in combo box. I dont want to make it editable.

    Here is code for my combo box

    Code:
    {
     xtype: 'combobox',
     fieldLabel: 'Choose Country',
     store: states,
     queryMode: 'local',
     hideTrigger:true,             
     displayField: 'name',
     valueField: 'abbr'             
    }
    Please suggest how to achieve this

    Default

    For this you'd have to set the editable config to false so that the person could not type in the input. You'd have to capture the keydown event and then scroll to the first/best match.

    Default

    Code:
    Ext.create('Ext.form.field.ComboBox', {
        editable: false,
        enableKeyEvents: true,
        renderTo: Ext.getBody(),
        store: ['Volvo', 'Saab', 'Fiat', 'Audi'],
    
        listeners: {
            keyup: function(combo, event) {
                var key = String.fromCharCode(event.getKey()),
                    boundList = combo.getPicker(),
                    store = boundList.getStore(),
                    record = store.findRecord(combo.displayField, key);
    
                if (record) {
                    boundList.highlightItem(boundList.getNode(record));
                }
            }
        }
    });
