For a specific cell, output and then hide the output?

[cqcn1991]

In my notebook, I have some inter-result. When I run the notebook, I want to see them, but they are often too long, so I also want to hide them when the output is complete.

For example In https://cdn.rawgit.com/cqcn1991/Wind-Speed-Analysis/master/output_HTML/hongqiao_intl.html#6.2-Cross-validation,-to-select-the-number-of-Gaussian

I have cross validation results

They are important results, I want to see them when the cross validation is running, but they are too long, so when I output the HTML, and show it to others, I want to hide them. And redisplay them when requested.

Is there any way I can do this?

I think a good way is to change the output into a [+] button, and when you click it, the output is shown again.

I think that this is an interesting idea and I also missed sometimes such a functionality. I have made a small nbconvert template, here, to try to address this.

Since outputs can be collapsed in the notebook, the idea was simply to detect the collapsed state (available in cell metadata) and then hide/show the output div in the html file using a bit of javascript.

Just put the template in your templates directory and then issue jupyter nbconvert --template collapsed_outputs FILE.ipynb

You can find an example of conversion result here.

@jfbercher Interesting, I never notice that the collapsing feature in edit mode before. I know there is a collapse feature, but now it behaves quite differently as I remembered.

That's a good discovery for me, thanks.

Is there any magic command that could used to collapse a cell?
