Usage
Import form builder:
import FormBuilder from '@data-driven-forms/form-builder/form-builder';
and render the component with following props:
Props
render or children
({ ComponentPicker, PropertiesEditor, DropTarget, isValid, getSchema, children }) => React.Element
Use children or a render function to render the whole editor.
componentMapper
object
Data Driven Forms component mapper. See here.
builderMapper
object
A set of components that creates the form builder.
import { builderComponentTypes } from '../src/constants';
const builderMapper = {
FieldLayout,
PropertiesEditor,
FormContainer,
[builderComponentTypes.BUILDER_FIELD]: builderField,
BuilderColumn,
PropertyGroup,
DragHandle,
EmptyTarget
}
FieldLayout
({ children, disableDrag, dragging, selected }) => React.Element
A wrapper around a single field = BUILDER_FORM + DragHandle.
PropertiesEditor
({ propertiesChildren, validationChildren, addValidator, avaiableValidators, handleClose, handleDelete, hasPropertyError }) => React.Element
An editor.
FormContainer
({ children, isDraggingOver }) => React.Element
A wrapper around the form in the form column.
BUILDER_FIELD
({ innerProps: { hideField, snapshot }, Component, propertyName, fieldId, propertyValidation, hasPropertyError, ...props }) => React.Element
A wrapper around the field.
BuilderColumn
({ children, isDraggingOver }) => React.Element
A column.
PropertyGroup
({ className, children, title, handleDelete }) => React.Element
A wrapper around a single property group in the properties editor > validation.
DragHandle
({ dragHandleProps, hasPropertyError, disableDrag }) => React.Element
A drag handle. Is passed as a child to FieldLayout.
EmptyTarget
() => React.Element
EmptyTarget is shown when there are no fields created.
componentProperties
object
A mapper of editable properties for each component. A property is a object with following attributes:
attributes
Editable attributes of the component.
propertyName
string
Corresponds to an attribute in the schema.
label
string
A label shown for the property in the editor.
component
string
A component corresponding to a key in properties mapper.
disableValidators
Disables validator selection in PropertiesEditor
.
Automatically disabled in fields that are not registered in the form state.
disableInitialValue
Disables initial value field in PropertiesEditor
.
Automatically disabled in fields that are not registered in the form state.
Example
const LABEL = {
propertyName: 'label',
label: 'Label',
component: 'input'
}
const componentProperties = {
[componentTypes.TEXT_FIELD]: {
attributes: [LABEL, IS_REQUIRED]
},
[componentTypes.PLAIN_TEXT]: {
attributes: [LABEL],
disableValidators: true,
disableInitialValue: true
}
}
pickerMapper
object
A mapper of components available in the editor.
const pickerMapper = {
[componentTypes.TEXT_FIELD]: ({ component }) => <div>{component}</div>
}
propertiesMapper
object
A mapper of components available in component properties.
const propertiesMapper = {
input: ({ label, value, fieldId, innerProps: { propertyValidation }, ...rest }) => <input {...rest} />
}
mode
one of 'subset' | 'default' optional
If 'subset', options will be only editable to certain degree. See schemaTemplate.
schema
object optional
A Data Driven Forms schema. See here.
schemaTemplate
object optional
An original schema from which a subset is created. If not specified, editable boundaries will be created from the schema.
cloneWhileDragging
boolean optional
Components from the components list are being cloned when dragged.
debug
boolean optional
Turns on debug mode. Will show current field as a JSON object.
openEditor
boolean optional
Opens the first field on mount.
disabledAdd
boolean optional
Disables adding new fields.
disableDrag
boolean optional
Disables dragging.
Mappers
Form builder contains two mappers of components: PatternFly 4 and Material UI versions.
Material UI
import {
pickerMapper,
propertiesMapper,
builderMapper,
BuilderTemplate,
fieldProperties
} from '@data-driven-forms/form-builder/mui-builder-mappers';
Version 5
MUI-BUILDER is using MUI of version 5. To use version 4 (@material-ui/core
), please use the builder of version 0.0.12-rc1
.
PatternFly 4
import {
pickerMapper,
propertiesMapper,
builderMapper,
BuilderTemplate,
fieldProperties
} from '@data-driven-forms/form-builder/pf4-builder-mappers';
Example
render={({ isValid, getSchema, ...props }) => (
<BuilderTemplate {...props} className={classes.builderWrapper}>
<CodeEditor value={JSON.stringify(getSchema(), null, 2)} />
</BuilderTemplate>
)}
