Usage Considerations for Working with Records
Working with records using base components make Lightning Data Service available to you without additional configuration, but there are a few custom use cases to consider.
Consider the following use cases.
- To display a record form based on a record type, which includes picklist values based on the record type, get the record type Id.
- To notify a parent component about a successful record submission, dispatch and handle a custom event.
Picklist fields display values according to your record types. When working with
lightning-record-edit-form, you must provide a record type Id if you have multiple record types on an object and you don’t have a default record type. Otherwise, the default record type Id is used.
To retrieve record type information, use the

Display a record create form based on a record type by providing the
record-type-id attribute. This example shows a form that you can place on an account record page. The form displays fields, which include a picklist with values based on the given record type Id.
getObjectInfo module and a reference to the account object. The
recordTypeId getter returns the Id that matches the record type name
recordTypeInfos property returns a map of record type Ids that are available in your org.
lightning-record-view-form components come with event handling via
onerror attributes. To pass your form data to the container component, create a custom event.
Let’s say you have a container component
c-wrapper, and your form is in the component
c-account-creator. Let’s pass the Id of the new record to the container component. In
c-wrapper, create an instance of
When the record is created successfully, the
newrecord event is dispatched by the
onsuccess handler on
lightning-record-form, which then calls the
handleNewRecord method with the record Id.
createStatus property displays a message with the Id of the newly created record.
The Id is not available on the
submit event. Use the
success event to return the Id.
handleAccountCreated method handles the
