Add RecordForm Component with Docked Footer Support

Since InlineEdit is going to be deprecated. The form editing pattern is a Popover/Edit icon button for single input fields and the SLDS Form Edit mode for multiple field forms.

I propose creating a <Form> component that wraps form elements and allows adding a Docked Form Footer. The following is a mockup. Docked Footer should always be paired with Read/Edit mode of forms.

Consumers would still need to update inputs from read only variants to base inputs themselves, but I'm open to suggestions. I would be difficult to pass a prop down into the inputs directly since they may be nested in formatting. This might be a place to use React's context?

The primary issue with Docked Form footer is that it might need to be fixed to the bottom of the page and not scroll.

I need additional input from stakeholders.

Start by reviewing the SLDS Form Edit and Docked Form Footer references, along with the InlineEdit deprecation issue. Clarify the component API, Read/Edit behavior, context needs, and fixed-footer behavior with stakeholders before implementation. Done means the design and requirements are agreed and the component behavior is defined.
