allowBlank : false,
store : ['Business', 'Personal'],
typeAhead : true,
mode : 'local',
triggerAction : 'all',
emptyText :'-- Select category --',
selectOnFocus :true
});

var active = new Ext.form.Checkbox({
name : 'active',
fieldLabel : 'Active',
checked : true,
inputValue : '1'
});

var propsGrid = new Ext.grid.PropertyGrid({
el:'props-grid',
nameText: 'Properties Grid',
width:300,
autoHeight:true,
viewConfig : {
forceFit:true,
scrollOffset:2 // the grid will never have scrollbars
},
customEditors: {
'Category': new Ext.grid.GridEditor(comboCategory),
'Active' : new Ext.grid.GridEditor(active)
}
});

propsGrid.render();

propsGrid.setSource({
