How do I get the multifield count in a component AEM?

Question

Actually, I need to get the multifield count in the component, and then I need to use that count in the HTL. Is there any way to get the multifield count?

@ameen_dev HTL does not offer a way to get the list size either, however it allows getting interesting properties of the current item:

* index: zero-based counter (0..length-1);
* count: one-based counter (1..length);
* first: true for the first element being iterated;
* middle: true if element being iterated is neither the first nor the last;
* last: true for the last element being iterated;
* odd: true if count is odd;
* even: true if count is even.

e.g. If you want to display the whole list count

<sly data-sly-test.totalItems="${0}"></sly>
<sly data-sly-list.child="${resource.listChildren}">
    <sly data-sly-test.totalItems="${ childList.count }"></sly>
</sly>

${ totalItems } - this will give you the number of items in the list.

Hi @ameen_dev ,

You already might be using a model to get the multi data, that multi is returned as a list which you can iterate in HTL.

Since, your backend code Resource#listChildren will return an Iterator<Resource>, you will not be able to get the size of the list of children from there.

Either you can , make use of current item properties :

// iterate and check if thats the last item, if yes -> return the count
<sly data-sly-list.demo=“${demo123.items.listChildren}”> 
    <sly data-sly-test=“${demoList.last}”>  
     ${demoList.count}
</sly>

Or you can declare a variable for itemList and use .length :

<sly data-sly-list.item="resource.listChildren">
    <sly data-sly-list.itemList="item.listChildren">
        ${itemList.length} 
    </sly>
</sly>

Hope this helps!

Thanks,

Milind
