推荐答案

通常struts2中的struts checkboxlist会横向调整复选框.在大多数应用程序中，我们希望垂直显示复选框(逐行).为了将其对齐为垂直，我们必须执行以下操作

Normally the struts checkboxlist in struts2 diaply the check boxes horizontally. In most of application we want to display the check boxes vertically (line by line). For aligning this as vertical we have to do the following

  1. 你必须在你的 src 文件夹中创建一个目录模板

  1. You have to create a directory template in your src folder

使用您要创建的模板名称创建一个文件夹(垂直复选框)

Create a folder with the name of the template you want to create (vertical-checkbox)

将struts-2.1.6/src/core/src/main/resources/template/simple/checkboxlist.ftl文件复制到该目录下该文件内容如下.在您必须根据需要或喜欢此链接放置

Copy the struts-2.1.6/src/core/src/main/resources/template/simple/checkboxlist.ftl file to this directory content of this file is as follows. Before the you have to put a
tag as you want or like this link: http://codeglobe.blogspot.com/2009/09/struts2-align-check-box-vertical.html

<s:checkboxlist list="urllist" name="selectedValues" listKey="id" listValue="descrption" theme="vertical-checkbox"></s:checkboxlist>

这将为您提供一个垂直的复选框列表.唯一的区别是这里你必须指定和你在项目的src文件夹的模板目录中创建的目录相同的主题.

This will give you a vertical check box list. The only difference is that here you have to specify the theme which is same as the directory you have created in the template directory in the src folder of your project.
