leaflet-sidebar

A responsive sidebar plugin for Leaflet, a JS library for interactive maps.

Examples

Examples are available in the examples folder and on Github Pages:

• Basic example
• mapbox.js listing-markers example
• Example with 2 sidebars

Using the plugin

See the included examples for usage.

Usage

Add a content container somewhere in your document:

<div id="sidebar">
    <h1>leaflet-sidebar</h1>
</div>

Create a new L.Control.Sidebar and add it to the map:

var sidebar = L.control.sidebar('sidebar', {
    position: 'left'
});

map.addControl(sidebar);

The sidebar will be hidden on startup, use the following methods to show or hide it:

// Show sidebar
sidebar.show();

// Hide sidebar
sidebar.hide();

// Toggle sidebar visibility
sidebar.toggle();

// Check sidebar visibility
var visible = sidebar.isVisible();

If you want the sidebar to be visible on startup use the following snippet after adding it to the map:

setTimeout(function () {
    sidebar.show();
}, 500);

Do not call show() directly after adding the control to the map. The setTimeout will work around some CSS quirks for you.

The content of the sidebar can be changed dynamically:

sidebar.setContent('test <b>test</b> test');

If you need more flexibility you can use sidebar.getContainer() to get the content container element or use e.g. jQuery on the <div id="sidebar"> element.

Options

The sidebar can be configured with these options:

• position: Can be left (default) or right and shouldn't need explaining.
• closeButton: Can be true (default) or false. If true a close button will be added to the sidebar.
• autoPan: Can be true (default) or false. If true the map will be shifted when the sidebar is shown.

Events

Whenever the visibility of the sidebar is changed, an event is fired on the sidebar instance. You can listen for these events like this:

sidebar.on('hidden', function () {
    console.log('Sidebar is now hidden.');
});

Available events:

• show: Show animation is starting, sidebar will be visible.
• shown: Show animation finished, sidebar is now visible.
• hide: Hide animation is starting, sidebar will be hidden.
• hidden: Hide animation finished, sidebar is now hidden.

Note that the shown and hidden events depend on transitionend/webkitTransitionEnd which might not be supported by all browsers yet.

Compatibility

leaflet-sidebar was developed to work with Leaflet 0.6.4 and should work fine with v0.7 too. I have no information whether it works well with older versions.

The leaflet-sidebar plugin has been tested on the following systems and browsers:

• Ubuntu: Firefox, Chrome
• Mac OS X: Firefox, Chrome, Safari
• Android 4.3: Firefox, Chrome, Opera
• iOS: Safari
• Windows XP: Internet Explorer 6 (failed!)
