Column: Here you can select the column whose articles you want to list.
Set a reference page: Here you can assign an individual source or target page to the module.
Individual template: Here you can overwrite the standard mod_articlelist template.

The frontend module “Random Image” adds a random image from a certain selection of images to the website. You can select single images or complete folders as source. Existing metadata are evaluated.
Source files: Here you can select multiple files or folders. The images contained in a folder are automatically included in the selection.
Image size: Here you can define the dimensions of the image and the scaling mode.
| Relative format | |
|---|---|
| Proportional | The longer side of the image is adjusted to the given dimensions and the image is proportionally reduced in size. |
| Fit to frame | The shorter side of the image is adjusted to the given dimensions and the image is proportionally reduced in size. |

<div class="mod_randomImage block">
<figure class="image_container">
<a href="…" title="…" data-lightbox="8e0a5c">
<img src="…" alt="" itemprop="image">
</a>
</figure>
</div>

The module has no enclosing HTML markup.
Individual template: Here you can overwrite the standard mod_html template.
With the frontend module “RSS Reader” you can subscribe to any RSS feed and insert it into your website, e.g. to integrate the news feed of contao.org.
Open the module administration in the backend and select the module “RSS reader”.
Feed URLs: Here you can enter one or more RSS feed URLs.

| Template | Declaration |
|---|---|
rss_default |

<!-- indexer::stop -->
<div class="mod_rssReader block">
<div class="rss_default_header">
<h1><a href="…" target="_blank" rel="noreferrer noopener">…</a></h1>
<div class="description">…</div>
</div>

<h2><a href="…" target="_blank" rel="noreferrer noopener">…</a></h2>
<div class="description"><p>…</p></div>
</div>
<div class="rss_default odd">
<h2><a href="…" target="_blank" rel="noreferrer noopener">…</a></h2>
<div class="description"><p>…</p></div>
</div>
<div class="rss_default last even">
<h2><a href="…" target="_blank" rel="noreferrer noopener">…</a></h2>
<div class="description"><p>…</p></div>
</div>
</div>
<!-- indexer::continue -->
Using the rss_items_only template, the frontend module generates the following HTML code:

<h2><a href="#" target="_blank" rel="noreferrer noopener">#</a></h2>
<div class="description"><p>…</p></div>
</div>
<div class="rss_items_only odd">

An existing module can be selected for each starting point. The module “Root page dependent modules” can then be be inserted in the layout at the desired position to output the various contents.
