How to force a new row in the Gallery card

The example for the gallery includes a row with two images following a by row with a single image. I would like to be able to do this but cannot seem to find the way to start a new row: my first row would be two images in portrait format, and the second row has a single image in landscape format.

Is there a keyboard combination for this?

Which example are you referencing?

The gallery layout is completely automatic, the only control that’s available is changing the order of images. The layout rule is fit 3 images per row but never leave a single image on the last row so you can end up with 2x2, or 3x2x2 for example but never 2x1 or 3x1.

Thanks for the quick reply. I was referring to this: Editor cards which is 2+1, I think. How can I do this?

I can’t really contribute to any code on this, but the Tumblr gallery editor is quite nice to use – let’ just ignore the HTML it spits out.

I’m not sure how that example has ended up like that because it’s not possible to create galleries in that configuration inside the editor.

That would explain things! I was hoping I could use something like select an image and press a key to start a new row – having worked on an importer, I know that the rows are technically hard-coded.
