How to render images in rails3 select

问题:

I want to render dropdown list in form with images as options. How to achieve this in rails3?

回答1:

I like the msdropdown. You can add the path for the image in the title tag:

<select>
  <option value="1" title="#path for the image">first</option>
  <option value="2" title="#path for the image">second</option>
   ...
</select>

In Rails, you can add the title doing something like:

<%= f.select(:yourcolumn, Model.all.map{|p| [p.name, p.id, :title => p.image_url(:thumb)]}

I have faced a similar problem some time ago: generate HTML <select> with title inside each <option> to apply the msDropDown plugin

Check out this plugin http://www.marghoobsuleman.com/jquery-image-dropdown there is no option to do it directly in Rails.
