问题描述

我想以图像作为选项以表格形式显示下拉列表.如何在rails3中实现这一目标?

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

推荐答案

我喜欢 msdropdown .您可以在title标签中添加图像的路径:

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>

在Rails中，您可以添加标题，例如:

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)]}

前段时间我遇到了类似的问题:

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