You could use this plugin: http://www.sencha.com/forum/showthread.php?28318-Fit-to-parent&highlight=fitToParent

Use the 'fit' layout on the container, and set autoheight and autowidth to false on the child panel. The fit layout should take care of making the components inside it automagically 'fit'.

You can also try below code:

autoHeight: true
