Optimizely Forms is only supported by MVC-based websites and HTML5-compliant browsers.
You can extend the functionality of each form. This feature:
Lets an editor set configuration values for a form as extra metadata. Access this field on a form container from **All Properties** view > **Settings** tab.
Renders that metadata as a `
data-epiforms-metadata` attribute on the root element of the \<form> tag in edit view.
You can write code to modify the form based on the metadata. For example:
Change the layout of elements from vertical to horizontal. To do this, in the metadata, an editor inserts **horizontal**.
Change the background color based on metadata.
