## Install

### Bundle the Gem

    gem 'activeadmin_pagedown'
    
### The Stylesheets

Add the import to active_admin.css.scss:

    @import "active_admin_pagedown/base"
    
### The Javascript

Add the following to active_admin.js.coffee to load the Pagedown javascript:

    //= require active_admin_pagedown/base
    
If you want to use the simple default intializer for Pagedown, add the following as well:

## Usage

Now you can use the `pagedown_text` input via the `:as` option:

    form do |f|
      f.inputs do
        f.input :body, :as => :pagedown_text
        f.actions
      end
    end
    
Then you should see in your ActiveAdmin form:

## Caveats

* Only will work with 1 field per page at the moment. The Pagedown JS looks for specific dom ids, which is hard coded in the input right now.
* There is no image uploader. Pagedown on its own does not provide one, but it should be possible to add hooks to support it
