Re: How to build a dynamic navigation bar

[puschteblume]

Here is my code that works for me. I put the navigation bar in a panel.
<wicket:panel>
   <span wicket:id="mainNavList">
     <span wicket:id="navigationItem" >
       <a href="#">
         <span wicket:id="navigationLabel"></span>
       </a>
     </span>
   </span>

</wicket:panel>

And the java class looks like this:

public class MainMenuListView extends ListView<INavigationItem> {

   private static final long serialVersionUID = 1L;
   protected static Logger logger = 
Logger.getLogger(MainMenuListView.class);
  
   public MainMenuListView(String id, List<INavigationItem> dataList) {
       super(id, dataList);
   }
  
  
   @Override
   protected void populateItem(ListItem item) {
       INavigationItem navItem = (INavigationItem) item.getModelObject();
       ResourceModel rModel = new ResourceModel(navItem.getResourceKey());
       BookmarkablePageLink pageLink = new 
BookmarkablePageLink("navigationItem", navItem.getNavTargetClass());
       item.add(new BookmarkablePageLink("navigationItem", 
navItem.getNavTargetClass()).add(new Label("navigationLabel", rModel)));
   }

}

They need the same wicket:id yes, but that doesn't mean that they need the same

behaviour they need. Just make sure they all have the same id :)

Thanks for the quick reply.

Wouldn't this force all links to have the same wicket ids ("linkid")?
I'd like to be able to have the line items look like this:

<ul wicket:id="list">
        <li> # Link01 text here </li>
        <li> # Link02 text here </li>
        <li> # Link03 text here </li>
</ul>

Assuming this lil code

add( new ListView("list", linkList )
{
        public void populateItem(ListItem item)
        {
                item.add( (Link)linkList );
        }
});

You'd have the html look something like this

<ul wicket:id="list">
        <li> # Link text here </li>
</ul>

Just remember to add whatever you want to the item, and not just use
add(...).

Emne: How to build a dynamic navigation bar


Hello, 
  
I want to be able to build a left-side dynamic navigation bar based on
user
permissions. For example, if the user does not have access to the Prices
page, I do not want to show the Prices link on the navigation bar. Also,
since the link will point to a Wicket page, it has to be a Wicket link. 

This is how I would like the NavBar to appear: 

                <div id="mainNav">
                        <ul>
                                <li> Home </li>
                                <li> Prices </li>
                                <li> Contracts </li>
                                <li> Products </li>
                                <li> Transactions </li>
                        </ul>
                </div>

I tried using ListView, but I could not get it to work, as it forces the
wicket id of the line items to be all the same. 


Thanks in advance.
