Question

I have a textarea used in my extjs form . I want the text inside the textarea wrap to next line before it comes to the end of width .

tDescription = new Ext.form.TextField({
    fieldLabel:"Description"
    ,name:"Description"
    ,tabIndex:3
    ,width:250
    ,height:90
    ,allowBlank:false
    ,disableKeyFilter:true
});

I think you must change to new Ext.form.TextArea, becouse this class creates a multiline text field
