如何从collection_check_boxes对齐输入和标签? [英] How to align input and label from collection_check_boxes?

问题描述

我正在使用 collection_check_boxes ，并且在对齐复选框和文本时遇到问题.这是我的代码:

I am using collection_check_boxes and have problems with aligning checkbox and text. This is my code:

<div class="col-md-4">
  <%= f.collection_check_boxes :dog_ids, Dog.all, :id, :name %>
</div>

表单显示如下:

[checkbox1]
  text1

[checkbox2]
  text2

[checkbox3]
  text3

我正在尝试对齐输入和标签，但是没有成功.我已经看到了以下问题，但对我不起作用:

I am trying to align input and label but didn't have success. I have seen these question but it don't work for me: Align checkboxes for f.collection_check_boxes with Simple_Form

我想做到这一点:

[checkbox1] text1

[checkbox2] text2

[checkbox3] text3

谢谢您的帮助！

推荐答案

collection_check_boxes 的定义:

collection_check_boxes(object, method, collection, value_method, text_method, options = {}, html_options = {}, &block)

最后一个参数允许您执行以下操作:(这完全符合您使用collection_check_boxes的要求)

The last argument permits you to do something like this: (this does exactly what you want using collection_check_boxes)

<%= f.collection_check_boxes(:dog_ids, Dog.all, :id, :name) do |b| %>
  <div class="row">
    <%= b.label(class: "check_box") do %>
      <div class="col-xs-4">
        <%= b.check_box(class: "check_box") %>
      </div>

      <div class="col-xs-8">
        <%= b.object.name %>
      </div>       
    <% end %>
  </div>
<% end %>

还有另一种方法:通过CSS设置复选框输入和标签的样式.

There is another method too: style your checkbox input and your label from css.

为了获得更好的CSS特异性，我将添加一个名为复选框列表"的新类:

For a better css specificity I will add a new class named 'checkbox-list' to:

<div class="col-md-4 checkbox-list">
  <%= f.collection_check_boxes :dog_ids, Dog.all, :id, :name %>
</div>

.checkbox-list input[type="checkbox"] {
  display: inline-block;
  width: 10%;
}

.checkbox-list input[type="checkbox"] + label {
  display: inline-block;
  margin-left: 10%;
  width: 80%;
}
