There is currently no option to save grids/guides that could be reused elsewhere.
For now I can only copy the frame that already has set up grid, but if I would have like 100 of them and wanted to change grid slightly then I would have to do this for 100 other frames…
Ooh yeah, I’d love to be able to copy paste guides. Or if you could save the guides (and layouts in general) in a component board that you could slot other elements inside. Right now you have to detach a layout component to place other elements inside it.
@Losio I ended up building a plugin for exactly this — Guides & Grids Manager. Not on
Penpot Hub yet, but you can install it today by pasting this into the plugin
manager: https://guides-and-grids-manager.girafic.net/manifest.json
This is SO COOL @girafic. Such a capable plugin. Are you going to share it on the Hub? I’m planning on writing some tutorials that feature guides, and it would be great to share your plugin there.
Thx you, I’ve already submitted to the Penpot hub, it takes some days for review.
@LauraKalbag Plugin in now in the Penpot Hub → Penpot Plugin | Guides & Grids Manager
