Build Custom Lightning Web Components for Service Documents
Customize templates for your specific business and branding needs by creating custom
components with Lightning web components (LWCs).
If you need a component for your document template that isn’t available in Document Builder standard components, you can easily customize templates for your specific business and branding needs. Creating custom components is simple with LWCs. LWCs for service documents require specific print styling, so if you built custom components for other platforms, such as Field Service Mobile, you must make components for Document Builder.
