Nudges will be displayed in the same order that they occur on the Stream page (from top to bottom). This will be in the chronological series in which you have created them. Reordering the Nudges in a Stream and the sequence the show in on your website is very easy.
To reorder your Nudges, click on the dots beside the Nudge you want to move. Now you can drag and drop the selected Nudge into the correct place in your stream. Remember, as a result, reordering your Nudges will also change the sequence in which your Nudges will show in on your connected website.
