The RSS (really simple syndication) element is used to display frequently updated published works, such as blog entries, news headlines, etc. To get started, drag the RSS element into your message.
After that, click on the element and you will see the styling options on the left side of the editor. Here, you can put the RSS URL input.
Paste a valid RSS URL and click on the refresh icon. You can use website like RSS validator to check whether the URL follows the rules of the RSS specifications. This will ensure that the content will display on the messages editor properly.
After loading the content, you will by default be presented with the title, description and link. In the options on the left, you can choose how many items to load and in what layout. If you choose a horizontal layout, you will have the option to choose how many per row you can display. It would be best not to exceed 2, as to not squish the content too much.
You can also choose to add more content in your RSS block, like publish date or images, by clicking on the dropdown. You may also want to rearrange the order of the content, or choose to delete content by clicking the bin icon.
Lastly, you will also have the option to style every element loaded in the RSS block, such as images, titles, text, links and more. Just click on a specific element in the RSS block, to style it like a regular element using the styling options on the left side of the editor.
Remember that you can always change the source or add more articles, by clicking the RSS icon in the breadcrumbs menu, as shown below.
