Methods, systems, and computer readable media for providing an extended reality (XR) user interface. A method for providing an XR user interface occurs at a user device executing an XR application. The method comprises: receiving content information about a hierarchical container structure; obtaining, via the XR application, spatial information about a physical and/or virtual environment; generating, using the content information, at least one immersive visual element for visually representing the hierarchical container structure, wherein each of the at least one immersive visual element represents a container, a sub-container, or a data element of the hierarchical container structure; and providing, using the XR application, the spatial information, and a display, the at least one immersive visual element by augmenting a depiction of the physical and/or virtual environment so that a user can enter the at least one immersive visual element, access elements of the hierarchical container structure from within the at least one immersive visual element, and view the physical and/or virtual environment through the at least one immersive visual element.
