Salesforce introduced an amazing new feature to the Lightning Record Pages called Dynamic Forms. It seamlessly integrates the functionalities of the Lightning Record Pages and page layouts.
Now you do not need to change different page layouts to change fields for the UI. You can use fields individually on the record pages to create your own Dynamic form. You can add a single field or select a whole section from the page layout to add to the record page.
There are a lot of benefits to using Dynamic forms. You are no more required to use the Classic page layout. You can change the layout on the Lightning App Builder itself. In order to hide/show the fields or sections, you can use the component’s visibility rules because each field or section would act as a separate component and can be handled or placed anywhere on the Lightning record page.
