Menus and navigation in Wordpress - Deep Dive

Overview - Menus and navigation

What is it?

Menus and navigation in WordPress are tools that help visitors move around a website easily. They are lists of links usually shown at the top, side, or bottom of a site. These menus guide users to important pages like Home, About, or Contact. WordPress lets you create, organize, and display these menus without coding.

Why it matters

Without menus and navigation, visitors would get lost and frustrated trying to find information on a website. Menus make websites user-friendly and keep people engaged longer. They also help search engines understand your site structure, improving visibility. Good navigation is like clear street signs in a city, making the experience smooth and enjoyable.

Where it fits

Before learning menus, you should understand basic WordPress concepts like pages and posts. After mastering menus, you can explore advanced topics like custom menus, responsive navigation, and menu plugins. This fits into the broader journey of building and customizing WordPress websites.

Understanding WordPress Menus Basics

Concept: Learn what menus are and how WordPress uses them to organize links.

Menus in WordPress are collections of links to pages, posts, or custom URLs. You create menus in the WordPress dashboard under Appearance > Menus. Each menu can have multiple items arranged in order. Menus appear in specific spots on your site called menu locations, like the header or footer.

Result

You can create a simple menu with links to your main pages and assign it to a location so visitors see it on your site.

Understanding that menus are just organized link lists helps you see navigation as a simple but powerful way to guide users.

Creating and Assigning Menus

Concept: How to build a menu and place it on your website using WordPress tools.

In the WordPress dashboard, go to Appearance > Menus. Click 'Create New Menu', give it a name, and add pages or custom links. After arranging items, assign the menu to a theme location like 'Primary Menu'. Save changes and visit your site to see the menu appear where you chose.

Result

A visible navigation menu appears on your site, letting visitors click links to different pages.

Knowing how to create and assign menus empowers you to control your site's navigation structure without coding.

Using Menu Hierarchies and Submenus

🤔Before reading on: Do you think submenus are separate menus or part of the main menu? Commit to your answer.

Concept: Menus can have nested items called submenus to organize links under categories.

In the menu editor, drag a menu item slightly to the right under another item to create a submenu. This creates a dropdown effect on the site, grouping related links. For example, under 'Services', you can list 'Web Design' and 'SEO' as sub-items.

Result

Visitors see dropdown menus that reveal more options when hovering or clicking a main menu item.

Understanding menu hierarchies helps you organize complex navigation clearly, improving user experience.

Custom Links and Menu Item Settings

🤔Before reading on: Can menu items link only to pages, or can they link anywhere? Commit to your answer.

Concept: Menus can include custom links and have settings like opening in a new tab.

Besides pages and posts, you can add any URL as a menu item using 'Custom Links'. You can also edit each item’s settings to add titles, CSS classes, or choose if the link opens in a new tab. This flexibility lets you link to external sites or special pages.

Result

Menus can link to any web address with customized behavior, expanding navigation possibilities.

Knowing you can add custom links and tweak settings makes menus adaptable to many navigation needs.

Intermediate

Menu Locations and Theme Integration

Concept: Themes define where menus can appear; understanding this helps place menus correctly.

Each WordPress theme supports certain menu locations like header, footer, or social menu. In the menu editor, you assign your menu to one of these locations. If a theme supports multiple menus, you can create different menus for different spots. Some themes also style menus differently based on location.

Result

Menus appear in the correct places on your site, matching the theme’s design and layout.

Knowing how themes control menu locations helps you plan navigation placement for best user impact.

Responsive Menus and Mobile Navigation

🤔Before reading on: Do you think desktop menus work the same on mobile devices? Commit to your answer.

Concept: Menus must adapt to different screen sizes for good mobile usability.

Most modern themes include responsive menus that change layout on small screens. This often means collapsing into a hamburger icon that expands on tap. You can customize or add plugins to improve mobile navigation, ensuring menus remain easy to use on phones and tablets.

Result

Visitors on mobile devices see a simplified menu that is easy to open and navigate.

Understanding responsive navigation is key to making your site accessible and user-friendly on all devices.

Custom Menu Walkers and Advanced Filters

🤔Before reading on: Do you think WordPress menus are fixed, or can developers change how they render? Commit to your answer.

Concept: Developers can customize how menus are output using PHP classes called walkers and filters.

WordPress uses a 'walker' class to generate menu HTML. By creating a custom walker, developers can change the markup, add icons, or insert special classes. Filters let you modify menu items dynamically, like adding badges or hiding items based on user roles. This allows deep customization beyond the dashboard.

Result

Menus can have unique designs and behaviors tailored to complex site needs.

Knowing about walkers and filters unlocks powerful customization options for professional WordPress development.

Under the Hood

WordPress stores menus as collections of menu items in the database, linked to a menu ID. Each item references a page, post, or URL. When rendering, WordPress uses PHP functions to fetch the menu items for a location and outputs HTML lists. The walker class controls how this HTML is structured. CSS and JavaScript from the theme style and add interactivity to menus.

Why designed this way?

Menus were designed to be flexible and user-friendly for non-coders, while allowing developers to customize deeply. Storing menus as data objects separate from pages lets users rearrange navigation without changing content. The walker system provides a clean way to customize output without altering core code.
