The number of lower level categories that can be surfaced within the Power Pages Employee Self-Service Portal knowledge base may depend on the specific settings and configuration of your platform. However, it may be possible to change this limit to display more than 5 lower level categories.
Here are some steps you can take to try and adjust this setting:
1. Access the category settings: Log in to the Employee Self-Service Portal as an administrator and navigate to the category settings section.
2. Locate the category display options: Look for options related to the display of categories, such as "category layout" or "category view".
3. Check for a limit setting: See if there is a setting that limits the number of subcategories displayed per parent category. If you find this setting, try adjusting the limit to a higher number, such as 10 or 15.
4. Save the changes: Once you have made the changes, save the category settings.
5. Check the result: Navigate to a page that displays the lower level categories and check if the new limit is being applied.
If you are unable to find a setting that allows you to adjust the number of lower level categories displayed, you may need to consult the documentation or support resources for your specific platform to see if there is a way to modify this behavior.
