combo adding items

[pinidbest]

How do I add items to a combofield dynamicly?
I cant find any sample that does not invlove a store.

If this the case how do I create an empty store and add model instance to it so that the combo will show these items?

You can use a simple array store and populate the array as needed
use store.loadData(data) to populate the store

var data = [
        {"abbr":"AL", "name":"Alabama"},
        {"abbr":"AK", "name":"Alaska"},
        {"abbr":"AZ", "name":"Arizona"}
    ];


// The data store containing the list of states
var states = Ext.create('Ext.data.Store', {
    fields: ['abbr', 'name'],
    data : [ ]
});

// Create the combo box, attached to the states data store
Ext.create('Ext.form.ComboBox', {
    fieldLabel: 'Choose State',
    store: states,
    queryMode: 'local',
    displayField: 'name',
    valueField: 'abbr',
    renderTo: Ext.getBody()
});

states.loadData(data);
