How to show Category with n childrens in a form

Hi All,
I want to show the categories in a form which has n no. of childrens
with n no. of chain. for ex.

category1
—category2
—category3
—category4
—category5
—category6
—category7
—category8
… and so on…

what is a best way to show this so that user can easily recognize what
category is he selected. idon’t want to show all the categories in same
drop-down because it gets difficult for user to find required category
and also he also not came to know that whcih parent category it belongs.

Regards,

use acts_as_category
acts_as_category (Version 1.0)

acts_as_category, is yet another acts_as plugin for Ruby on Rails

If everything is set up, you can actually use the plugin. Let’s say
you have trees like this and your model is called Category.

root1 root2
_ child1 _ child2
_ subchild1 \subchild3
_ subchild2 \subchild4
