Is there a Rails helper similar to link_to_remote but for a form check box instead of a link?

I'm working on a couple of user input forms -- one data entry, one search -- where I'd like to start off by displaying only top-level categories. Then, if a user checked one of the top-level categories, all the child categories would show for that top-level one. (Displaying all the child categories for every parent would be a bit overwhelming, it's a large list.)

I can see how to do this by making the category name a clickable link, and using link_to_remote, but that's not an expected UI for a form. I'd rather use a check box, but I'd like to avoid trying to write my own non-Rails-assisted Ajax from scratch if possible.

Thanks.

You can use the #remote_function helper that generates the javascript that #link_to_remote uses:

<%= check_box_tag :foo, '1', params[:foo], :onclick => remote_function(:url => ...) %>
