Tips for personalizing the sidebar on your WordPress site and incorporating a collapsible menu feature

Is there a way to customize the sidebar in WordPress so that all the categories and their children are easily accessible? For example, on https://www.w3schools.com, clicking on the header category "HTML" displays all related links in the left sidebar.

I'm new to HTML and CSS. Can anyone provide more information on where I can find the HTML and CSS files in my WordPress site?

Where in WordPress can I make these changes?

Thank you in advance!

Utilizing Nested Lists In the world of web design, nested lists are a common tool used to organize information in a structured way. The Classic and Default WordPress Themes make use of nested lists to display sidebar content. Nested lists consist of multiple unordered lists embedded within each other, creating a hierarchical structure. Here's a basic example:

<ul><!-- open main list -->
<li>Title of Section One
     <ul>
      <li>Apple</li>
      <li>Orange</li>
      <li>Banana</li>
     </ul>
</li><!-- close section one list -->
<li>Title of Section Two
     <ul>
      <li>Beef</li>
      <li>Chicken</li>
      <li>Fish</li>
     </ul>
</li><!-- close section two list -->
<li>Title of Section Three
     <ul>
      <li>Carrot</li>
      <li>Celery</li>
     </ul>
</li><!-- close section three list -->
</ul><!-- close main list -->

Customization is key when working with nested lists. Each "section" can be given a unique CSS ID or class to control its appearance. Whether you want every section to look the same or have distinct styles, it all comes down to how you implement CSS rules.

While nested lists are commonly used in WordPress Themes, they are not required for building your sidebar. However, if you choose to follow this pattern, understanding how nested lists function is essential. For tips on styling your WordPress nested lists, read our guide on Styling Lists with CSS.
