collapse cell in jupyter notebook

Question

I am using ipython Jupyter notebook. Let\'s say I defined a function that occupies a lot of space on my screen. Is there a way to collapse the cell?

I want the func

Answer 1

Create custom.js file inside ~/.jupyter/custom/ with following contents:

$("").appendTo("head");
$('.prompt.input_prompt').on('click', function(event) {
    console.log("CLICKED", arguments)   
    var c = $(event.target.closest('.cell.code_cell'))
    if(c.hasClass('collapse')) {
        c.removeClass('collapse');
    } else {
        c.addClass('collapse');
    }
});

After saving, restart the server and refresh the notebook. You can collapse any cell by clicking on the input label (In[]).
