Assets are pieces of content that are saved in a central location that can be used on multiple pages or in multiple sites. If the asset content is changed that change is applied to all pages using it.
A form asset can be set up to collect information from users that can be submitted via email with the option to also collect it in a database within the CMS. You can configure form elements, email messages, and success or failure messages.
While this functionality is still available in Omni CMS, we have created the Image Gallery snippet that is simpler to use instead.
