Set "active" class in navigation sidebar #75
Description
I am implementing a simple portal using CppCMS. The master page has a simple sidebar for navigational purposes based on the W3C example.
My master template looks like this (mainly the sidebar template is of interest):
<% c++ #include "data/content.hpp" %>
<% skin defskin %>
<% view master uses content::master %>
<% template title() %>
<%= title %>
<% end template %>
<% template page_content() %>
Override Me
<% end template %>
<% template sidebar() %>
<div class="sidebar">
<a class="active" href='<% url "/" %>'>Home</a>
<a href='<% url "/news" %>'>News</a>
<a href='<% url "/users" %>'>Users</a>
</div>
<% end template %>
<% template render() %>
<html>
<head>
<link rel="stylesheet" href="/css/style.css">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title><% include title() %></title>
</head>
<body>
<% include sidebar() %>
<div class="content">
<h1><% include title() %></h1>
<% include page_content() %>
</div>
</body>
</html>
<% end template %>
<% end view %>
<% end skin %>
What is the appropriate/recommended way of setting the class="active" attribute for the URL of the current view/page? Is there a mechanism in the template engine that allows me to set the attribute on the appropriate menu item in the master template?
