[jQuery] Appending content in order

[Feijó]

consider that html: <div class=main>     <div class=sub></div>     <div class=sub></div>     <div class=sub></div>     <div class=sub></div>     <div class=sub></div> </div> I need to append a new <div class=sub></div> as the 2nd, 3rd, middle, etc. Append() add after the last one. How can I do that? Its possible? Thanks Feijó
