Notes
In Salesforce, a custom component in the Lightning App Builder page is a reusable piece of functionality that can be added to a Lightning page layout to provide additional functionality and customization options.
Custom components are built using the Lightning Component Framework, which is a modern, standards-based framework that allows developers to create complex, responsive user interfaces with reusable components.
Custom components can be created to provide a wide range of functionality, such as displaying data from external systems, automating business processes, or providing custom user interfaces for specific tasks.
Once a custom component has been created, it can be added to a Lightning App Builder page layout by dragging and dropping the component onto the page. Users can then configure the component by setting various properties and attributes, such as data sources, filters, or layout options.
Overall, custom components in Salesforce provide users with a powerful and flexible way to customize their Lightning pages and create tailored user experiences. By leveraging the Lightning Component Framework, developers can create reusable components that can be easily added to multiple pages and adapted to meet the specific needs of their users.
