Example: Paginating Mapper-based snippets with sortable headers

import net.liftweb.mapper.view.Paginator
class Requests extends ModelSnippet[Request] {

  // Parameters: the MetaMapper, default sort field, and (headerName, field) tuples
  val paginator = new Paginator(Request, this, Request.id,
                                "id" -> Request.id,
                                "nature" -> Request.nature,
                                "client" -> Request.client,
                                "dispatcher" -> Request.dispatcher,
                                "priority" -> Request.priority,
                                "comment" -> Request.comment
  )
  

  def list(xhtml: NodeSeq) = 
    bind("prefix", paginator.paginate(xhtml),  ... )
}

View

nav: prefix is for navigation links. allpages is the list of page numbers, linked. The ’ | ’ is used as the separator in this example; you can choose something else if you like.
In the table header use the sort prefix sortable headers. For example .. gets linked with a link that sorts by id. When clicked a second time it sorts in descending.
