ui.page_sidebar(
    sidebar
    *args

    window_title=MISSING
    lang=None
    theme=None
    **kwargs
)

Create a page with a sidebar and a title.

Parameters

sidebar : Sidebar: Content to display in the sidebar.
*args : TagChild | TagAttrs = (): UI elements.
title : Optional[str | Tag | TagList] = None: A title to display at the top of the page.
fillable : bool = False: Whether or not the main content area should be considered a fillable (i.e., flexbox) container.
fillable_mobile : bool = False: Whether or not fillable should apply on mobile devices.
window_title : str | MISSING_TYPE = MISSING: The browser’s window title (defaults to the host URL of the page). Can also be set as a side effect via panel_title.
lang : Optional[str] = None: ISO 639-1 language code for the HTML page, such as "en" or "ko". This will be used as the lang in the <html> tag, as in <html lang="en">. The default, None, results in an empty string.
theme : Optional[str | Path | Theme | ThemeProvider] = None: A custom Shiny theme created using the Theme class, or a path to a local or online CSS file that will replace the Bootstrap CSS bundled by default with a Shiny app. This file should be a complete bootstrap.css or bootstrap.min.css file. For advanced uses, you can also pass a Tagifiable object. In this case, Shiny will suppress the default Bootstrap CSS. To modify the theme of an app without replacing the Bootstrap CSS entirely, use include_css to add custom CSS.
****kwargs** : TagAttrValue = {}: Additional attributes passed to layout_sidebar.

Returns

: Tag: A UI element.

Examples

#| standalone: true
#| components: [editor, viewer]
