I ran the code to hide the cells of Jupyter notebook and it worked. Any ideas on how to display the cells again?
from IPython.display import HTML
HTML('''<script>
var code_show=true; //true -> hide code at first
function code_toggle() {
$('div.prompt').hide(); // always hide prompt
if (code_show){
$('div.input').hide();
} else {
$('div.input').show();
}
code_show = !code_show
}
$( document ).ready(code_toggle);
</script>
''')
This is what I am seeing
Basically, if you restart Anacond and run the notebook again you see all the cells

I've been trying to hide the input of a code cell in Jupyter by adding the tag hide-input to it. However, it doesn't seem to be working. What is the most up to date way of doing it?
According to the latest documentation youi can use the:
{toggle}
directive to hide/un-hide elements in a Jupyter Notebooks, as noted in 1.
The example given is:
:show:
Some hidden toggle content!
If you just want to hide any input code cell, I would recommend you to use:
# Specific code we want to hide:
# ==============================
# #hidden
from IPython.display import HTML
password="xxxxx"
# ==============================
# Necessary script to hide the cell:
# ==============================
HTML('''<script>
code_show=true;
function code_toggle() {
if (code_show){
$('.cm-comment:contains(#hidden)').closest('div.input').hide();
} else {
$('.cm-comment:contains(#hidden)').closest('div.input').show();
}
code_show = !code_show
}
$( document ).ready(code_toggle);
</script>
To show the code hidden: click here.''')
# ==============================
This solution was originally provided by Damian Kao. And works perfectly.
It also adds the toggle-on/off functionality: When you run this cell, the code will be hidden by default. But you can show it by clicking on the link.
I really appreciate the "code_folding" feature in RMarkdown. However, what I really need is to have the code show all the time and toggle the display on the output.

Here is a basic example.

Is there a way to toggle the output rather than the code? The best (but not ideal) solution I have thought of is to add collapse=TRUE to the chunks, but then the code and the output still display at the same time.

Full control over which chunks should be folded
Fold all chunks that contain more than one line of code/output
1. Full control over which chunks should be folded
I wanted to have the same functionality as well and did the following:
I created a JavaScript that looks as follows:
$(document).ready(function() {
$chunks = $('.fold');
$chunks.each(function () {
// add button to source code chunks
if ( $(this).hasClass('s') ) {
$('pre.r', this).prepend("<div class=\"showopt\">Show Source</div><br style=\"line-height:22px;\"/>");
$('pre.r', this).children('code').attr('class', 'folded');
}
// add button to output chunks
if ( $(this).hasClass('o') ) {
$('pre:not(.r)', this).has('code').prepend("<div class=\"showopt\">Show Output</div><br style=\"line-height:22px;\"/>");
$('pre:not(.r)', this).children('code:not(r)').addClass('folded');
// add button to plots
$(this).find('img').wrap('<pre class=\"plot\"></pre>');
$('pre.plot', this).prepend("<div class=\"showopt\">Show Plot</div><br style=\"line-height:22px;\"/>");
$('pre.plot', this).children('img').addClass('folded');
}
});
// hide all chunks when document is loaded
$('.folded').css('display', 'none')
// function to toggle the visibility
$('.showopt').click(function() {
var label = $(this).html();
if (label.indexOf("Show") >= 0) {
$(this).html(label.replace("Show", "Hide"));
} else {
$(this).html(label.replace("Hide", "Show"));
}
$(this).siblings('code, img').slideToggle('fast', 'swing');
});
});
Since I am no JS crack it might not be perfect, but it does what it is supposed to.
Include it in your Rmd file:
<script src="js/hideOutput.js"></script>
I also wrote some CSS definitions to style the button:
.showopt {
background-color: #004c93;
color: #FFFFFF;
width: 100px;
height: 20px;
text-align: center;
vertical-align: middle !important;
float: right;
font-family: sans-serif;
border-radius: 8px;
}
.showopt:hover {
background-color: #dfe4f2;
color: #004c93;
}
pre.plot {
background-color: white !important;
}
After including both, the JS file and the stylesheet, you can hide chunks by wrapping a div container around them with one of the following classes:
Hide output only
<div class="fold o">
```{r}
...
```
</div>
Hide source code
<div class="fold s">
```{r}
...
```
</div>
Hide both
<div class="fold s o">
```{r}
...
```
</div>
The script detects the type of each chunk (e.g. source code, text output or plot output) and labels the buttons accordingly.
The result looks like this:
2. Fold all chunks that contain more than one line of code/output
Here is a version of the script that adds the folding feature to all chunks that are longer than one line:
$(document).ready(function() {
$plots = $('img.plot');
$chunks = $('pre').has('code');
$chunks = $chunks.filter(function(idx) {
return $(this).children('code').outerHeight(false) > parseInt($(this).css('line-height'));
});
$chunks.each(function () {
if($(this).hasClass('r')) {
$(this).append("<div class=\"showopt\">Show Source</div><br style=\"line-height:22px;\"/>");
} else {
$(this).append("<div class=\"showopt\">Show Output</div><br style=\"line-height:22px;\"/>");
}
});
$plots.each(function () {
$(this).wrap('<pre class=\"plot\"></pre>');
$(this).parent('pre.plot').prepend("<div class=\"showopt\">Show Plot</div><br style=\"line-height:22px;\"/>");
});
// hide all chunks when document is loaded
$chunks.children('code').toggle();
$('pre.plot').children('img').toggle();
// function to toggle the visibility
$('.showopt').click(function() {
var label = $(this).html();
if (label.indexOf("Show") >= 0) {
$(this).html(label.replace("Show", "Hide"));
} else {
$(this).html(label.replace("Hide", "Show"));
}
$(this).siblings('code, img').slideToggle('fast', 'swing');
});
});
Just include it with <script src="js/hideAll.js"></script> and you don't need to wrap div containers around your code chunks.
One thing you have to add in your Rmd document though is the following global chunk option:
```{r, echo = F}
knitr::opts_chunk$set(out.extra = 'class="plot"')
```
It is needed to identify graphical output.
How about this lo-fi solution?
<details><summary>Click here</summary>
Some text
```{r code}
# even code
print("Hello world!")
```
</details>
Not mine, but I like it.
A quick an hacky way to toggle a section (not necessarily code):
Enclose the sections to toggle with <div class="toggle"><button>TOGGLE_TEXT</button> and <\div> in your .Rmd file
1. How many users are in the second, but not the first, user table?
<div class="toggle"><button>Solution</button>
```{r}
setdiff(user2, user) %>% nrow()
```
</div>
Put this at the bottom of the .Rmd file (or ideally in a .js file linked to all your pages).
<script>
$(".toggle").click(function() {
$(this).toggleClass("open");
});
</script>
Put this in your .css file (you'll have to play with the height for your button).
.toggle {
height: 1.55em;
overflow-y: hidden;
}
.toggle.open {
height: auto;
}
I straight up copied the javascript from the source of another Rmarkdown document where I set code_folding: show. I saved the javascript as py_code_folding.js and added <script src="py_code_folding.js"></script> to the top of my Rmarkdown document. The only limitation is that I had to hardcode in my javascript whether I want the blocks to be initially shown or hidden.
window.initializePythonCodeFolding = function(show) {
// handlers for show-all and hide all
$("#rmd-show-all-code").click(function() {
$('div.r-code-collapse').each(function() {
$(this).collapse('show');
});
});
$("#rmd-hide-all-code").click(function() {
$('div.r-code-collapse').each(function() {
$(this).collapse('hide');
});
});
// index for unique code element ids
var currentIndex = 10000;
// select all R code blocks
var rCodeBlocks = $('pre.python');
rCodeBlocks.each(function() {
// create a collapsable div to wrap the code in
var div = $('<div class="collapse r-code-collapse"></div>');
if (show)
div.addClass('in');
var id = 'rcode-643E0F36' + currentIndex++;
div.attr('id', id);
$(this).before(div);
$(this).detach().appendTo(div);
// add a show code button right above
var showCodeText = $('<span>' + (show ? 'Hide' : 'Code') + '</span>');
var showCodeButton = $('<button type="button" class="btn btn-default btn-xs code-folding-btn pull-right"></button>');
showCodeButton.append(showCodeText);
showCodeButton
.attr('data-toggle', 'collapse')
.attr('data-target', '#' + id)
.attr('aria-expanded', show)
.attr('aria-controls', id);
var buttonRow = $('<div class="row"></div>');
var buttonCol = $('<div class="col-md-12"></div>');
buttonCol.append(showCodeButton);
buttonRow.append(buttonCol);
div.before(buttonRow);
// update state of button on show/hide
div.on('hidden.bs.collapse', function () {
showCodeText.text('Code');
});
div.on('show.bs.collapse', function () {
showCodeText.text('Hide');
});
});
}
$(document).ready(function () {
window.initializePythonCodeFolding("show" === "show");
});

I am trying to put a autocomplete functionality on a text input , this is working fine if css is not present but if css is present this is not working .
This is my fiddle
and this is my code
var sourcesymbols = ["ONE", "TWO", "THREE"];
jQuery(document).ready(function() {
$("#stock_name").autocomplete({
source: sourcesymbols,
messages: {
noResults: '',
results: function() {}
}
});
});
Could you please let me know how to resolve this .
when you use CSS styling for the text box you will hide the data list (auto complete list data) you can try an alternative as shown in this link - Datalist
I want to save some space for my 14 inch screen. What should I write in e.g. ipython_notebook_config.py to trigger this?
If it doesn't already exist, create a file named custom.js in /Users/YOURUSERNAME/.ipython/profile_default/static/custom/
(You may have to run ipython profile create, if you have never run this command.)
In custom.js, put the following lines of JavaScript
$([IPython.events]).on("app_initialized.NotebookApp", function () {
$('div#header').hide();
});
If you would like to also hide the toolbar by default, use these lines of JavaScript instead
$([IPython.events]).on("app_initialized.NotebookApp", function () {
$('div#header').hide();
$('div#maintoolbar').hide();
});
If you have a recent IPython, like v3.0.0 or higher, and are seeing only sporadic success with this method, you'll need to hook into the RequireJS dependency loader, and put the following in your common.js:
require(['jquery'], function($) {
$('#header-container').hide();
});
common.js is loaded at the bottom of the page, so there's no need to wait for the DOM ready event, i.e., $(function() { ... }).
For further discussion see my answer at Turn off auto-closing parentheses in ipython and its comments.
if you are using Anaconda3, please do:
update your C:\Anaconda3\Lib\site-packages\notebook\static\custom\custom.css
.container{ width:100% !important; }
div#site{ height: 100% !important; }
update your C:\Anaconda3\Lib\site-packages\notebook\static\custom\custom.js, and we add a shortcut ctrl+ for toggle the header
$([IPython.events]).on('notebook_loaded.Notebook',function(){
$('#header').hide();
IPython.keyboard_manager.command_shortcuts.add_shortcut('ctrl-`',function (event) {
if (IPython.notebook.mode == 'command') {
$('#header').toggle();
return false;
}
return true;
});
