EXT-JS adding elements dynamically into FormPanel

I have a FormPanel that includes a bunch of TextField, I also 开发者_StackOverflowadd more to it dynamically using FormPanel.add(), FormPanel.doLayout(), however the height doesn't readjust itself, so extra textfields are not visible. what's going on? thanks

Either the FormPanel (and all higher level containers) have to be auto height (autoHeight: true) so that the browser will handle sizing, or else you will need to recalculate the height after adding and set it programmatically. I've done it both ways, depending on the layout.
