How to add item to Extjs panel at exact position

Question

I am adding an item to Extjs panel.

this.add(new_el);
this.doLayout();

It works fine. but in some cases I have to add {new_el} at exact position, not last.

For example penultimate one.

Can't find easy method in Extjs 3.2.1

Solution

You should use insert() instead of add().

Mypanel.insert(0,cmp1);
Mypanel.insert(4,cmp2);
