Not exactly sure what changed from Beta 2 to Beta 3 form components.
This worked fine in Beta2 but in beta3, labelWidth : 0 makes the 'selectfield', 'textfield' width smaller (50%) than what it should be.
For example, with beta 2, textfield width was about 320px but, with beta3 it's only 160px with labelWidth=0.
Thanks for the help.Code:{ xtype : 'selectfield', options : [ {text : 'Option1', value : '0'}, {text : 'Option2', value : '1'}, {text : 'Option3', value : '2'} ], placeHolder : 'Select an option', labelWidth : 0 }
