Sightly - Empty check on list HTL - aem

Question

How to check the empty list on Sightly?
I wanted to prevent render the item-list DIV if there was no item on itemImgaeList. But it returns me one (1) always if there were no items while trying with -
LIST_SIZE_PRINT = "${container.itemImgaeList.size}"; // retrun 1
HTL:
<div data-sly-test="${container.itemImgaeList.size > 1}">
<sly data-sly-list.imageList="${container.itemImgaeList}">
<div class="item-list">
<picture>
<img alt="${imageList.qlImageText}" src="${imageList.qlImagePath}" />
</picture>
</div>
</sly>
</div>
Any help?

Answer 1

data-sly-list can be used for implementing the above requirement of rendering the list elements only when the list is not empty.
The use of 'data-sly-test' is not required for checking a list, as the check for emptiness is done inherently by data-sly-list.
Here is a working example using data-sly-list:
<div class="item-list" data-sly-list.item="${container.itemImgaeList}">
<picture>
<img alt="${item.qlImageText}" src="${item.qlImagePath}" />
</picture>
</div>
