CakePHP select default value in SELECT input

Question

Using CakePHP   I have a many-to-one relationship  let s pretend it s many Leafs to Trees   Of course  I baked a form to add a Leaf to a Tree  and you can specify which Tree it is with a drop-down box   tag  created by the form helper   The only thing is  the SELECT box always defaults to Tree  1  but I would like it to default to the Tree it s being added to   For example  calling example com leaf add 5 would bring up the interface to add a new Leaf to Tree  5   The dropdown box for Leaf tree id would default to  Tree 5   instead of  Tree 1  that it currently defaults to   What do I need to put in my Leaf controller and Leaf view add ctp to do this
