Actual Post:

Hi,

I need to check size of the list in sightly. I need to display UI only when it has more than 2 items in list. Any idea?

Thanks,

Arya.

    Depending on the methods of your list-object you can do something like this:

    <div data-sly-test="${yourList.size > 2}">

    ...

    </div>

      Hi Feike,

      Thanks. I have gone through sightly tutorials. But I didn't find this attribute. Actually we have size() for java.util.ArrayList. Can I use all of List methods like mylist.<ListMethod> ? Where can I find these tutorials? I have seen only count,first,last,index etc.

       

      Thanks,

      Arya.

        hi arya,

        You can just the methods from the object, whether that is List, Array etc.

        So if you have .size(), you can use .size. If you have .length() or .count(). You can use .length or .count.

        Hope this helps.

        Inside your list, you can use things like ${itemList.count}, but this only works inside data-sly-list:

        <ul data-sly-list="${currentPage.listChildren}">

        <li>${item.name} Page ${itemList.index} of ${itemList.count}</li>

        </ul>

          ".size" works for List Objects
