The Text Box dashboard item is used to display rich text within a dashboard.
You can provide text by uploading file in the RTF format.
To do this, go to the Text Box's Options menu and click the ellipsis button in the Text field.
This invokes the Open dialog, which allows you to locate the RTF file.
To learn about exporting the Text Box dashboard item, see Exporting.
The loaded RTF file's content in the Text Box can differ from the original RTF file's layout because of RTF to HTML conversion limitations and browser specifics.
