Multi page app documentation

Panel

Replacing the Column objects seems to work:

import panel as pn

pn.extension(sizing_mode="stretch_width")

pages = {
    "Page 1": pn.Column("# Page 1", "...bla bla bla"),
    "Page 2": pn.Column("# Page 2", "...more bla"),
}


def show(page):
    main_column.objects = [pages[page]]


starting_page = pn.state.session_args.get("page", [b"Page 1"])[0].decode()
page = pn.widgets.RadioBoxGroup(
    value=starting_page,
    options=list(pages.keys()),
    name="Page",
    sizing_mode="fixed",
    button_type="success",
)
main_column = pn.Column()
pn.bind(show, page, watch=True)
page.param.trigger("value")
pn.state.location.sync(page, {"value": "page"})

ACCENT_COLOR = "#0072B5"
DEFAULT_PARAMS = {
    "site": "Panel Multi Page App",
    "accent_base_color": ACCENT_COLOR,
    "header_background": ACCENT_COLOR,
}
pn.template.FastListTemplate(
    title="As Single Page App",
    sidebar=[page],
    main=[main_column],
    **DEFAULT_PARAMS,
).servable()
