Jupyter notebook: split screen vertically (i.e. add cell horizontally)

Question

Is it possible to add a cell on the side of another cell, splitting the screen vertically? This seems very useful when comparing two lists of things.

I don't see this options supported out of the box, so I am guessing it would require some extra js?

This is now possible in JupyterLab. See this example:

...there is a menu item to create a new side-by-side view of that same notebook that will remain synchronized with the other view:

Note that JupyterLab will eventually replace Jupyter Notebook. See this answer.

You can right-click a file tab, and select, "New View for Notebook."

This functionality has been merged on GitHub and will be in the 3.2 release. Go to View -> Render side by side

Is there a project for an "independant scroll" extension so that there is no empty spaces? When a cell is short but its output tall or the converse. – Louis-Amand Feb 09 '23 at 14:46

This is not possible at the moment (April 12th 2016), but there is a ticket in the Jupyter github issues that mentions that "soon" we will be able to open several notebooks in the same browser tab; That would allow for the side by side comparisons you are looking for.

I think the OP was referring to having multiple windows into the same file. For instance, I am adding documentation cells at the top of my notebook, so I'd like to keep that cell open while I use the search feature to find things I'm documenting. If I could open the same notebook under multiple tabs, that would probably do the trick. – RufusVS Sep 05 '18 at 17:14
@RufusVS can't you though? In the file browser mode, click the file you want to view, let it open up, then just click the same file again; then you'll have two browser tabs that you can move to separate side-by-side windows. I'm not sure they synchronize their content (I mean that if you make changes in one I don't think the changes show in the other), but that might be unnecessary for the OP. – CrepeGoat Feb 25 '19 at 17:48
@CrepeGoat : I misread the OP. It looks like meto was trying to get a side-by-side view of two cells for comparison, which is different from what I was looking for. (OP did say split "vertically" which I glossed over). I was looking more for a "notebook split-screen editor", which wouldn't work without synchronization between views. Even a "collapse all cells" function might work for me. (only expanding the cells I was working with) – RufusVS Feb 25 '19 at 19:27
@RufusVS gotcha. Well from my uninformed perspective, I imagine a synchronous multi-window feature isn’t an outlandish request; go ahead and see if you can pitch it to the dev. team for future work, it’d be a nice addition. – CrepeGoat Feb 26 '19 at 02:09
