Let’s take an example of adding a lightning component on Account Record (the same process can be followed to add a lightning component on other standard or custom objects record).

  1. Go To Account -> Select any record -> Click on setup icon -> Click on Edit Page
  2. Account record page is now open
  3. Search component: MassFileDownloadLightningComponent or you will see the component in the custom section on the left side menu.
  4. Drag and Drop MassFileDownloadLightningComponent to Anywhere in record page wherever you want to display download files and attachment records.
  5. Click on Save
  6. Click on Activate and follow instruction of activation (If record page is not activated).
