Details

Verbatim text displays a character string as monospaced code in a shaded rectangle.

To create reactive verbatim text, render the text in the server function with the decorators @render.text, just as you would to display normal text. Then place the rendered text in the ui with ui.output_verbatim_text().

By default, ui.output_verbatim_text() will display nothing when the string to display is empty. To ensure that ui.output_verbatim_text() displays an empty shaded rectangle as a placeholder even when when the string to display is empty, set placeholder=True.

See Text to display string values as normal text.

Variations

Placeholder rectangle when string is empty

Verbatim text with a placeholder when the string to display is empty (see Details above).
