Form input components

Reactodia provides basic built-in components to edit entity or relation properties in a form:

Form input component	Description
<FormInputList />	Form input to edit multiple values in a list of specified single value inputs.
<FormInputText />	Form input to edit a single value as a plain string with an optional language.

warning

Currently form input components are considered unstable so there might be breaking changes in their API in the future.

Example: overriding input to a multiline text field
