Hide a Page Editor block at selected screen sizes when a section feels too long, crowded or image-heavy on a smaller screen.
Open the public event page while signed in as an organiser with page-editing access, then select Edit Page.
Use the responsive toolbar to choose Desktop, Laptop, Tablet, Mobile (Large) or Mobile (Small).
Open Blocks, find the block, select its ... menu and choose Hide.
The change saves automatically. Wait for Saved and check the affected views before selecting Exit Page Editor. If a save error appears, resolve it before leaving.
The menu changes to Show when the block is hidden for the selected view. Use Show to make it visible again. Desktop settings provide the default. Smaller views inherit settings from larger views unless they have their own override. After hiding a block on Laptop, Tablet or Mobile (Large), check the smaller views too. Hiding on Desktop can affect every view without its own override.
