Here is a sample of my code.

PHP Code:

var nestedList = new Ext.NestedList({
            
name:'list',
            
toolbar: {title:strDefaultTitle},
            
items: [{
            {
                    
texthtml,
                    
title'A',
                    
items: [{
                            
xtype'fieldset',
                            
title'A1'
                        
},{
                            
xtype'fieldset',
                            
title'A2'
                        
},{
                            
xtype'fieldset',
                            
title'A3'
                        
},{
                            
xtype'fieldset',
                            
title'A4'
                        
},{
                            
xtype'fieldset',
                            
title'A5'
                        
}]                
            },{
                    
texthtml,
                    
title'B',
                    
items: [{
                            
xtype'fieldset',
                            
title'B1'
                        
},{
                            
xtype'fieldset',
                            
title'B2'
                        
}]                
            }]
}); 
some how, when a user selects List A, I need the child of A to scroll down to A3 automatically. Anyone know how this can be done?
