data-sly-repeat define max item via cq dialog

Thanks all for the insightful suggestions.

Will go with Java/JS method since unable to achieve with HTL although the properties.maxItems type was changed to Long.

May be its not written to support type conversions and works only within the indices of the collection.

data-sly-repeat:

• Iterates over the content of each item in the attribute value and displays the containing element as many times as items in the attribute value, allowing to control the iteration through the following options:
  • begin - iteration begins at the item located at the specified index; first item of the collection has index 0
  • step - iteration will only process every step items of the collection, starting with the first one
  • end - iteration ends at the item located at the specified index (inclusive)

Go with Ravi/Arun's approach.

Hi,

You can have Java or JS code to control the size of the list based on the value entered in cq:dialog

Ex:

Add the below JS code in a file

"use strict";
use(function () {
  let n = properties.get("colNum", 0);
  return {
  columns: [...Array(100)] // empty, iterable, array of size n
  };
});

<div
  data-sly-use.config="<JS-file-name>"
  data-sly-list="${config.columns}">
  <div class="6u">
  <h3>Accumsan</h3>
  <ul class="alt">
  <li><a href="#">Nascetur nunc varius</a></li>
  <li><a href="#">Vis faucibus sed tempor</a></li>
  <li><a href="#">Massa amet lobortis vel</a></li>
  <li><a href="#">Nascetur nunc varius</a></li>
  </ul>
  </div>
</div>
