Is there a way to trigger the sidebar button?

you can call openNav() anc closeNav() from javascript. One way is to create an dummy html pane and change the object.

import panel as pn

html = pn.pane.HTML("")
button_open = pn.widgets.Button(name="openNav")
button_close = pn.widgets.Button(name="closeNav")

def open(event):
    html.object = f""" <script> openNav(); </script>"""
button_open.on_click(open)

def close(event):
    html.object = f""" <script> closeNav(); </script>"""
button_close.on_click(close)

vanilla = pn.template.VanillaTemplate(title='toogle_nav')
vanilla.sidebar.append(html)
vanilla.main.append(button_open)
vanilla.main.append(button_close)

pn.serve(vanilla)

How to make the sidebar hidden as default?
#3

Is there a way to do the equivalent in the Material template, to close the nav / sidebar after its populated with some panel objects?

There is a little snippet of javascript in the template definition, but not obvious to me how to engage?

{% if nav %}
var drawer = mdc.drawer.MDCDrawer.attachTo(document.querySelector(’.mdc-drawer’));
var topAppBar = mdc.topAppBar.MDCTopAppBar.attachTo(document.getElementById(‘header’));
topAppBar.setScrollTarget(document.getElementById(‘main’));
topAppBar.listen(‘MDCTopAppBar:nav’, function() {
drawer.open = !drawer.open;
// Ensure bokeh layout recomputes layout
window.dispatchEvent(new Event(‘resize’));
});

drawer.open = true;
{% endif %}

Thanks for any help

John
