data-sly-repeat define max item via cq dialog

I am trying to use data-sly-repeat and need to define the max item to repeat. I though I could use the following HTL but if i replace the number with properties from the dialog (maxItems - sling:resourceType="granite/ui/components/coral/foundation/form/numberfield"), the component breaks with error Cannot get DefaultSlingScript: Operands are not of the same type: comparison is supported for Number types only.

Is there a simple way of using only HTL to achieve this? I also tried ${properties.maxItems @ context='number'} but no luck

Thanks in advance.

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>

Thanks. I have a Java sling modal that returns the items. I would like to use the HTL only if possible.

If the number is replace with the value from the cq dialog, it will return the same error

Cannot get DefaultSlingScript: Operands are not of the same type: comparison is supported for Number types only.

</ul>

try to use typehint as Long for number field item.

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

htl-spec/SPECIFICATION.md at master · adobe/htl-spec · GitHub

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.
