Dynamic Posts widget allows you to select from the various items style for posts and adjust and design individual items in the Items tab, which is populated when any predefined Item style is selected.
If you don't want to use predefined items style, then you have an option in the Dynamic Posts widget to create a custom Elementor Template. Follow along with me to see how to create a template.
In Items Style, Choose Elementor Template and click the plus icon to create a new template.
Now you can create the template where you need the post objects such as featured image, title, content, terms, etc., as you add in the item's style.
You can add any of this information using Widgets and Tokens. Once you are done with the template, save it and set it in the item's style.
