Hideable default sidebar
This example demonstrates hideable state. Sidebar toggler is moved outside the sidebar and added to navigation bar. You can have this button anywhere - content, card, page header or navbar. The only condition here is proper class names.
Sidebars overview

Sidebar - vertical area that displays onscreen and presents widget components and website navigation menu in a text-based hierarchical form. All sidebars are css-driven - just add one of css classes to the .sidebar container, and sidebar will change its width and color. No js, css only. Although sidebar type is based on css, buttons do their job with JS - they switch necessary classes in .sidebar container. Below you'll find summarized tables with all available button and sidebar container classes. By default, the template includes 6 different sidebar types and combinations:

1. Default sidebar

Default template sidebar has 300px (~18.75rem) width, aligned to the left (to the right in RTL version) and has dark blue background color. All navigation levels are based on accordion or collapsible functionality, open on click. Supports 2 versions: fixed (default) and static (in static layout only). Both versions use default browser sidebars, but support custom scrollbars such as perfect scrollbar component.

2. Mini sidebar

Mini sidebar has 56px width, which is calculated dynamically (icon size + double padding). No text in parent level of menu items, aligned to the left (to the right in RTL version) and has dark blue background color. Sidebar changes the width on hover, no additional changes. It is required to add .sidebar-main-resized class to the .sidebar container if you want to have it collapsed by default. This class is responsible for sidebar width and main navigation. By default all components except main navigation are hidden in mini sidebar. Can be used with main sidebar only.

3. Secondary sidebar

Main sidebar has 300px width or 56px (if .sidebar-main-resized class added). Secondary sidebar has the same fixed width of 300px, which is similar to default and right sidebars, so different sidebar components can be placed to all sidebar types. Main and secondary sidebars can contain any content - menu, navigation, buttons, lists, tabs etc. Secondary sidebar can be either collapsed or hidden.

4. Right sidebar

Right sidebar layout includes additional sidebar displayed on the right (left in RTL direction) side. It is displayed as an additional component with 100% height, similar to other sidebars. Right sidebar is visible by default, but can be collapsed or hidden.

5. Right/Secondary sidebars

Secondary and Right sidebars can be used together, so basically it is a 4 column layout. The width of any sidebar doesn't affect other layout columns, they all have independent width controls. Refer to the table below for more information.

6. Content (component) sidebar

Usually sidebar is not a part of content and mainly used for navigation. Limitless allows you to use sidebar outside and inside content area. Content sidebar isn't based on grid and has the same width as other sidebars, this means all sidebar components can be placed inside content sidebar. Supports left and right positioning and can be either stretched to fill all available height or height that depends on sidebar content height.

Button classes
Overview

This table displays all optional button classes, responsible for the sidebar appearance. Depending on the sidebar type, add one of these classes to any button or link and this element will handle sidebar control. Multiple controls are also available - add as many sidebar controls as you wish. Please note: these classes don't change sidebar markup, only CSS rules.

Button class Action
.sidebar-main-resize Resizable sidebar. Changes main sidebar width from default to mini. This button is added to all pages by default.
.sidebar-main-toggle Collapses/expands and/or hides/shows main sidebar. Used mostly in dual sidebar type to hide main sidebar.
.sidebar-right-toggle Toggles right sidebar - if right sidebar is shown, main sidebar width remains the same, whether it's in default or mini mode.
.sidebar-secondary-toggle Hides/shows or collapses/expands secondary sidebar. Secondary sidebar supports only toggle functionality and always has fixed width of 300px.
.sidebar-component-toggle Hides/shows content sidebars. Content sidebars aren't connected with other sidebars, so this is the only button that controls their visibility.
.sidebar-mobile-main-toggle Toggles main sidebar on mobile - slides from left to right.
.sidebar-mobile-secondary-toggle Toggles secondary sidebar on mobile - slides from left to right.
.sidebar-mobile-right-toggle Toggles right sidebar on mobile - slides from right to left.
.sidebar-mobile-component-toggle Toggles content sidebar on mobile - has full width by default, has no animation.
Example Markup

Default placement of sidebar control buttons is sidebar header:

            
								<!-- Main sidebar -->
								<div class="sidebar sidebar-dark sidebar-main sidebar-expand-lg">

									<!-- Sidebar content -->
									<div class="sidebar-content">

										<!-- Header -->
										<div class="sidebar-main-header sidebar-section">
											<div class="sidebar-section-body d-flex align-items-center"> 
												<h5 class="sidebar-main-title mb-0">Navigation</h5>
												<div class="ml-auto">
													<button type="button" class="[button classes]">
														<i class="icon-transmission"></i>
													</button>
												</div>
											</div>
										</div>
										<!-- /header -->

										[other content]

									</div>
									<!-- /sidebar content -->

								</div>
								<!-- /main sidebar -->

Here is an example of button inside navbar:

            
								<!-- Navbar placement -->
								<div class="navbar navbar-expand navbar-dark">
									<div class="navbar-brand">...</div>

									<ul class="navbar-nav">
										<li class="nav-item">
											<a href="#" class="navbar-nav-link sidebar-control sidebar-main-toggle">
												<i class="icon-menu"></i>
											</a>
										</li>
										...
									</ul>
								</div>
								<!-- /navbar placement -->
Sidebar classes
Overview

This table demonstrates all classes for sidebar container, responsible for the sidebar width and color. Almost all of these classes are mandatory, some of them are responsible for proper styling or have a specific code attached to this class (like .sidebar-main class, which has collapsible functionality). All classes can be combined depending on the type of sidebar:

Body class Description
.sidebar Default sidebar class, should be added in all layout types.
.sidebar-main Defines main sidebar. Mini sidebar (.sidebar-main-resized class) takes effect only if sidebar has .sidebar-main class. By default, all components except main navigation are hidden in mini sidebar.
.sidebar-main-resized Defines main sidebar in collapsed state
.sidebar-secondary Defines secondary sidebar. Has fixed 270px width and usually comes after main sidebar.
.sidebar-secondary-collapsed Defines secondary sidebar in collapsed state
.sidebar-right Defines right sidebar. Has fixed 270px width and appears on the right side from the main sidebar.
.sidebar-right-collapsed Defines right sidebar in collapsed state
.sidebar-component This class is required in content (or component) sidebar. Also requires .sidebar-component-left or .sidebar-component-right classes for proper spacing.
.sidebar-component-collapsed Defines content sidebar in collapsed state
.sidebar-light Defines light sidebar. This class can be applied to all sidebar types and positions.
.sidebar-dark Defines dark sidebar. This class can be applied to all sidebar types and positions. This class is also required for custom colors (see below).
.sidebar-dark.bg-* Defines sidebar background color. According to the custom color system, sidebar background color can be changed to one of the available colors by adding a proper class to the main sidebar container.
.sidebar-expand-[breakpoint] This class specifies when sidebar needs to be collapsed, basically when sidebar switches to mobile mode. Breakpoint should always be similar to navbar breakpoint for proper matching. Available breakpoints are: xl, lg, md and sm. This class is required.
.sidebar-main-unfold This class gets added when user hovers on mini sidebar. It controls resizable behaviour when main sidebar is collapsed. Has no effect on mobile since all sidebars on mobile have same width.
