The default left navigation for Vlge has a few items which cannot be removed. However, several can be added or removed based on your personal preferences.
👉 In General Settings, find the Deign & preferences section
👉 You can select/De-Select items that show the checkbox as available. Drag and Re-order items with the available "handle" on the left of the box.
Note: Items like Reservations must be enabled in order to be active here.
⭐️ Also - For additional customization: You can hide or reorder things in your Community Home Layout. Some of the items that are available in the left nav experience above can be hidden in the community layout when implemented in the left nav. Visit General Settings in the same Design & Preferences section and find Community Home Layout.
Also Note: If any item represents a feature for which a user does not have the role & permissions to access, it may be hidden.
