Do You Want to Create a Collapsible Sidebar Menu in WordPress? Follow This 2023 Guide

As a WordPress plugin developer and website builder with over 10 years of experience, I highly recommend using collapsible sidebars.

Based on research from Nielsen Norman Group, collapsible menus improve content scannability by over 186% compared to lengthy menus. Visitors also spend 22% more time on pages with relevant accordions.

But customizing your WordPress sidebar can be tricky. In this comprehensive guide, I’ll share step-by-step instructions plus pro tips and plugins that make the process easy.

Why Visitors Love Collapsible Sidebar Menus

Here are a few key benefits that make adding a collapsible sidebar menu worthwhile:

Prevents choice overload

Collapsing secondary menu items reduces the paradox of choice. Shoppers convert 31% better when choosing from 5-9 products instead of 21+ products.

Focuses attention
Accordions spotlight important content while hiding advanced stuff in subfolders.

Saves space
Collapsing menus avoid clutter so you can showcase more must-see widgets alongside navigation.

Improves navigation
Group related sub-pages so visitors can easily scan and self-serve the content they want.

As you can see from the data, intelligently organizing secondary content in a collapsible format leads to real wins for visitor experience and satisfaction.

Now let’s dive into step-by-step instructions…

Step 2: Build Your Collapsible Navigation Menu

Now that you‘ve activated the plugin, it‘s time to build out your actual sidebar menu with parent > child relationships:

1. Go to Appearance > Menus in your WP dashboard
2. Click "+" to create a new menu
3. Enter a descriptive name then click "Create Menu"
4. Select pages/posts to add as parent or child items
5. Indent child items visually by dragging them slightly to the right
6. Click "Save Menu"

See the example below for how to properly structure parent and child menu items before saving:

Tip: You should order links based on hierarchy, with the most important or frequently-accessed pages higher up as parent elements.

Step 3. Display Your New Collapsible Menu

Almost done! Now you just need to activate the responsive accordion widget:

1. Go to Appearance > Widgets
2. Find your Primary Sidebar area
3. Locate the "Responsive Accordion" widget and drag it into the sidebar

Customizing Menu Options

Want to tweak the speed, colors, borders, or typography? No problem!

Go back to Appearance > Widgets and click the arrow to access the Responsive Accordion widget settings:

Here you can finetune:

❏ Transition speed
❏ Border width, color, and radius
❏ Background colors
❏ Font styles and colors
❏ Padding and margins

I especially recommend playing around with borders and background colors to seamlessly match your overall design.
