我目前正在研究一个项目,我想创建一个HTML帮助页面,以向用户提供有关如何使用该应用程序的帮助和建议.
我要实现的是树形布局,因此在左侧,所有标题旁边都有加号.然后,当用户单击加号按钮或文本时,它将与该部分的相关内容一起展开.如果用户再次单击它,则现在已重新显示所有显示的项目.
我还没有找到任何有关如何执行此操作的不错的教程.
感谢您的任何帮助,您可以提供.
解决方法:
我花了一些时间来构建您所描述的快速树系统.有趣的小运动.复制并粘贴,在浏览器中打开(我正在使用FireFox).如果愿意,可以将DIV标签中的/-符号更改为图像.调整CSS的边距和内边距,使其无缝匹配.希望这可以帮助.
祝好运.
