Play Scala Framework multiple dropdown values selection

In my project I need to show drop down field with multiple items selection(more than one). I have done drop down with single selection by using this below code

userRegisterForm.scala.html 

@(userForm: Form[User],languages: Seq[(String, String)])

               @select(
                userForm("languages"),
                languages, 
                '_label -> "Choose Familiar Language", '_default -> "-- Choose Language --",
                '_showConstraints -> false            
            )

What I tried

I added 'multiple ->"multiple" in @select field

but it showed the all list items in drop down when page loaded.It is not like what I need.I have found this multiselect select - Play 2.0? answer from internet but I don't know how to implement those approaches in my project as I am a new to play framework. So anyone please help me to accomplish this task.

The HTML select tag doesn't have the capability you're asking for.

I'd use one of the plugins. Examples:

You can copy Play's select helper:

https://github.com/playframework/playframework/blob/master/framework/src/play/src/main/scala/views/helper/select.scala.html

into your views folder and modify it to produce the structure required by the plugin that you choose, include the .css and .js then there you have it. :)
