Setting Up the Basic Structure
Create a New Page and Enable Divi Builder:

Go to Pages > Add New in your WordPress dashboard.
Give your page a title and click on “Use Divi Builder.”
Choose a Two-Column Layout:

Select a layout with two columns – a narrower column on the left for the menu and a wider column on the right for the content.
Creating the Menu
Create a Custom Menu:

Navigate to Appearance > Menus.
Create a new menu for your documentation. This menu will contain links to the different sections or pages of your documentation.
Add Menu Items:

These items can be custom links, pages, or categories, depending on how your content is organized.
Add the Menu to Your Page:

In the Divi Builder, add a “Menu” module to the left column.
Select the menu you just created.
Setting Up the Dynamic Content Area
Use Divi’s Blog Module or Portfolio Module:

In the right column of your Divi layout, add a Blog or Portfolio module (depending on your content structure).
Configure this module to display posts, pages, or custom post types that represent different sections of your documentation.
Category or Tag-Based Filtering (Optional):

If your documentation is divided into categories or tags, you can set up the Blog or Portfolio module to filter content based on these.
Linking Menu to Content
Assign Categories/Tags to Content:

Ensure each piece of content (post, page, or custom post type) is assigned a unique category or tag that corresponds to your menu items.
Customize Menu Links:

When adding items to your menu, link each item to the corresponding category or tag page. For instance, if you have a menu item for “Installation,” it should link to the category or tag page that filters all content related to installation.
Final Steps
Styling and Customization:

Use Divi’s design options to style your menu and content area. Make sure they are visually distinct and easy to navigate.
Testing:

Test your layout thoroughly to ensure that clicking a menu item updates the content area with the relevant documentation section.
Publishing:

Once you are satisfied with the layout and functionality, publish your page.
Additional Notes
Ajax Loading (Advanced): For a more dynamic experience where content loads without refreshing the whole page, you would need to implement Ajax loading. This is a more advanced technique and might require custom coding or a plugin that supports Ajax.
Custom Post Types (Optional): For complex documentation, consider using custom post types to organize your content.
This approach allows you to create an interactive documentation page where users can navigate different sections easily. However, it might require some experimentation with Divi modules and WordPress settings to get it working perfectly for your specific needs.
