Hi Abdullah,

As of now, we don't have a specific implementation guide for using Metronic Demo39 (HTML- Billing SaaS) in Angular. However, you can still integrate it into your Angular project by following these steps:

1. Visit the Metronic Demo39 layout builder: Go to the Metronic Demo39 layout builder page at the following URL: https://preview.keenthemes.com/metronic8/demo39/layout-builder.html

2. Customize the layout: Use the layout builder to customize the design and components of Demo39 according to your requirements. You can add or remove sections, adjust layouts, and modify the styling.

3. Export the partials: Once you're satisfied with the customization, use the layout builder's export functionality to generate partial HTML files for different sections of the layout.

4. Integrate partials into your Angular project: In your Angular project, create corresponding components for each section of the layout. Copy the HTML code from the exported partials and paste it into the respective component templates.

5. Update component styles and scripts: Copy the CSS styles and JavaScript code related to the layout from the Metronic Demo39 assets. Update the component stylesheets and scripts in your Angular project accordingly.

6. Copy additional assets: From the Metronic Demo39 HTML version's zip package, extract any additional assets like images, fonts, or icons. Place these assets in the appropriate directories within your Angular project.

7. Adjust paths and references: Make sure to update any file paths or references in the copied HTML, CSS, and JavaScript files to match the directory structure and naming conventions of your Angular project.

8. Test and refine: Run your Angular project and test the integration of Metronic Demo39. Verify that the layout, styles, and functionality are working as expected. Make any necessary adjustments or refinements to ensure a seamless integration.

Please note that while this approach allows you to integrate the visual aspects of Metronic Demo39 into your Angular project, it may require additional effort to incorporate specific features or functionality present in the original HTML version.

Thanks
