Datefield modification Extjs4?

Is it possible to set the datefield in Extjs4 to be opend by default, to only have a sma开发者_JS百科ll calendar with today date selected, to somehow skip clicking a datefield button to open a calendar and to hide a textfield in datefield??

Yes, just use the Ext.picker.Date class, the field.Date uses it internally for the calendar.
