java - Play Framework: How do I change active class on route change -

i using play framework 2 java , bootstrap helper in project , want apply active class on sidebar link click. using side nav bar navigation , default 1 link has active class on page load, thats why in every time 1 link highlighted active link, how change class="active" on route or link change, there way check route path our html scala template file.

here side bar navigation code.

<ul class="nav nav-list">      <li class="active"><a href="/menu1">menu1</a></li>      <li><a href="/menu2">menu2</a></li>      <li><a href="/menu3">menu3</a></li> </ul> 

here routes file

get    /menu1          com.demo.project.controllers.democontroller.menu1()    /menu2          com.demo.project.controllers.democontroller.menu2()    /menu3          com.demo.project.controllers.democontroller.menu3() 

please give me suggestion on it!

finally got solution problem, sharing solution others too. firstly created method inside html scala template file.

@activelink(currentpath:string) = @{ if(request.path.equals(currentpath)) "active" } 

now need call above method inside class attribute of anchor tag.

<ul class="nav nav-list">  <li class="@activelink("/menu1")"><a href="/menu1">menu1</a></li>  <li class="@activelink("/menu2")"><a href="/menu2">menu2</a></li>  <li class="@activelink("/menu3")"><a href="/menu3">menu3</a></li> </ul>
