In the most basic sense, a low-fidelity prototype is often referred to as a “clickable” or “functional” wireframe. This is when one navigates between linked wireframe pages to understand how they are connected. But clickable wireframes can evolve into more advanced prototypes depending on the wireframe’s fidelity (gray box vs. graphic and text) and the complexity of interactions desired to present or test with stakeholders and/or users (accordion menus, carousels, etc.).
