Section breaks for very long CSS columns

Using CSS columns I can format contiguous data into columns without having to manually break it into sections. This is especially useful when displaying complex, dynamic content.
However when the columns' content is so long that their height is greater than the viewport, dividing into columns makes for a poor reading experience. When the reader reaches the bottom of one column they must manually scroll up to begin reading the next.
In traditional print layouts, readability issues with very long columns are generally mitigated by breaking the columns into sections that 'restart' the column. (Physical pages themselves form a natural separation that the endlessly scrolling webpage does not have). The image below shows how horizontal section breaks makes columnar content that is longer than the height of the viewport more readable.
(Note that by 'restart the columns' I mean that once you reach the end of a left-hand column section you then read the right-hand column of that section before scrolling down to read both columns of the next section. https://www.shutterstock.com/image-vector/newspaper-template... might illustrate it more clearly).
There are very few guarantees for the column content. It may contain any number of paragraphs, images, nested block elements, nested inline elements and so on. Example markup is shown below.
.columns {
columns: 2 200px;

I would like to automatically break my columns into regular sections after the columns reach a maximum height, as in the image above.
I have not found any property that controls the layout of CSS columns in this way. CSS regions look promising but have very poor browser support.
Computing the height of content with JavaScript and then inserting wrappers for each column block is probably possible, but not ideal. The content is dynamic and may change at any time, meaning the function must be run on every change. In addition the content may be very complex with sub elements that need to traverse section breaks, so naively inserting wrappers for each section will likely break the layout.
How can I automatically set section breaks for columnar content after a maximum height? (I am not married to the idea of CSS columns; perhaps a creative use of flex or inline-block will give the result I need).

There's actually a pretty simple solution using CSS columns. And the column-span attribute.
You can achieve all of this WITHOUT injecting anything into the content and simply styling HTML tags.
Basically, the CSS Columns Layout Module is intended to replicate print design layouts (like a newspaper) where the stylistic rule is that headlines should cross all columns of a story. Therefore any element with column-span: all will separate columns and cause the wrapping to reset. (notice the colors in my example show the wrap).
In this case, since you don't control the content its best to provide a common structure to your users. For example, I'd set H1, H2, H3 tags as well as <hr> and maybe some images to break columns. Allow your users to implement these tags as they normally would in writing and you'll achieve a nice layout. However, if they decide NOT to implement any of that stuff, that's up to them and you should let it wrap and cause a long scroll. (I might also suggest providing a preview so they can see what the result will look like)
Example of column-span
.columns {
margin: 30px;
columns: 2;
}
h1, h2, h3, h4, h5 {
column-span: all;
}
// simply to show where things wrap
h2 {
background-color: #eee;
padding: 5px 10px;
}
h5 {
border-bottom: 1px solid #ddd;
padding-bottom: 5px;
text-align: center;
}
p:nth-of-type(1) {
color: blue;
}
p:nth-of-type(2) {
color: green;
}
p:nth-of-type(3) {
color: orange;
}
p:nth-of-type(4) {

Using 'break-inside: avoid;' each paragraph
In the solution I attached, I gave each DIV a break-avoid class to avoid breaking in the middle of the paragraph.
Like you asked, if the paragraph is not over yet you can scroll down. I added a gray color that you can see in the paragraphs.
You can control when it will break and you can also insert a div into a div if you want it in sequence.
Hope the solution is effective for you.

Action when an element from collection get scrolled by

I have an unknown number of section blocks.
I use the titles of these automaticaly generated sections to populate the "tabs" container who follow the scroll (using sticky position).
What I need, is when I pass by one of the title contained in the sections, the same title from the "tabs" bar get the class "selected"so I indicate where the user is.
But what I've tried so far is only working partialy.
Here's a working example:
let titles = [];
$.each($('section>h3'),function(){
titles.push($(this).offset().top);
});
$(document).on('mousewheel DOMMouseScroll',function(e){
let winscrollpos = $(window).scrollTop();
$.each(titles,function(i,v){
if(winscrollpos >= v && winscrollpos < v+100) {
$('.deco-tab-title').eq(i).add('.selected').toggleClass('selected');
}
});
});

as you can see, the first title lose the class if you scroll to the end. But nothing else. And when you go back, the second title get the class. And overall, it doesn't work so well.

You might want to use the scroll event, which also captures using the scroll bar.
Scrolling height depends on the user agent. You should compare
[offset of current tab] < winscrollpos < offset[next tab] instead of [offset of current tab] < winscrollpos < offset[current tab] + 100.
Here's a working demo:
let titles = [];
$.each($('section>h3'), function () {
titles.push($(this).offset().top);
});
$(document).on('scroll', function (e) {
// 50 for the tab title height
let winscrollpos = $(window).scrollTop() + 50;
let titleElements = $('.deco-tab-title');
$.each(titles, function (i, v) {
if (winscrollpos >= v && (i === titles.length - 1 || winscrollpos < titles[i + 1])) {
titleElements.eq(i).addClass('selected');
} else {
titleElements.eq(i).removeClass('selected');
}
});

I have made the following fixes in your code:
add('.selected').toggleClass('selected'): chaining both functions this way cannot work. That's the reason why your titles were somehow blinking when selected. I've replaced this with the use of this version of toggleClass
I've added another list, nextTitlePos, in order to store, for each title, the position of the next one. For the last one, you can use any value greater than the end of your container (I've used Number.MAX_VALUE here to keep it simple, but if needed, you can use the end of the container as well.)
In the HTML code, there was also an extra <h3> tag, which was empty. This one was preventing title2 from being highlighted properly.
EDIT: I've replaced the event mousewheel with scroll as well (as mentioned by Shridhar Sharma in a comment below - thanks)
let titles = [];
$.each($('section>h3'),function(){
titles.push($(this).offset().top);
});
let nextTitlePos = [];
$.each(titles, function(i, v) {
if(i != 0) {
nextTitlePos.push(v);
}
});
nextTitlePos.push(Number.MAX_VALUE);
$(document).on('scroll DOMMouseScroll',function(e){
let winscrollpos = $(window).scrollTop();
$.each(titles,function(i,v){
let isSelected = winscrollpos >= v && winscrollpos < nextTitlePos[i];

I need to hide the old link data once a different link is clicked

Image of what is working:
.
I have links set up to where when you click it, some text data will show underneath it. Once a different link is clicked, I need the data from the previous clicked link to be hidden. here is what I have so far.
$('#area7').click(function () {
$('#output').empty();
factory.getAttrData()
.then((data) =>{
data.forEach(element => {
if (element.area_id === 7){
$('#output').append(attrHBS(element)); }
});
});
});
$(document).on("click", ".test", function(){
$(this).next().slideToggle();
});
//this is the appended code in handlebars
<div>
<h4 class ="test">
<a href="#">{{name}}_({{type_id}})
</a>
</h4>
<div id="show" class ="hidden">{{description}}
<br>
{{#if times}}{{times}}
{{/if}}
</div>

This is called an Accordion in many UI libraries. Here is a bare bones implementation. It uses delegated event handlers so dynamically adding to the DOM should not be an issue. You'll see that we can use the + operator in CSS and the .next() method from jQuery to target the collapsible sections. All you really need is to wrap these sections in a container that helps you identify them in the js.
$( document ).on( 'click', ' .accordion h4', function() {
let isOpen = $( this ).next( 'div').is(':visible');
$( ' .accordion h4 + div' ).slideUp();
if ( ! isOpen ) {
$( this ).next().stop().slideDown();
}
});
.accordion h4 {
cursor: pointer;
text-decoration: underline;
}
.accordion h4:hover {
text-decoration: none;
}
.accordion h4 + div {
display: none;
}

Smooth-scrollbar is not working on body element

I am working on a design where I have used smooth-scrollbar for smooth scrolling.
I have implemented it twice on my page, first on the entire page and second on a div element.
It is working fine on the div element but not on the body.
I am unable to scroll as the browser continuously displays the default scrollbar.
Here is my code that I've done so far

You have to set a height to each item otherwise it will not work
[data-scrollbar]{
height: 500px;/*<<<<<required*/
}
yay JS

Scrollbar.initAll({

How to make a search through H2 tags only

I have a single page with lots of H2 and paragraphs.
How to make a javascript/ajax (or other) search bar to search only through the H2 tags with dropdown suggestion and with no database?

You can use jQuery to search for occurrences with :contains(). The script also looks for the anchors (id) of the <h2> to link them.
// Make :contains() case insensitive
$.expr[":"].contains = $.expr.createPseudo(function(arg) {
return function(elem) {
return $(elem).text().toUpperCase().indexOf(arg.toUpperCase()) >= 0;
};
});
// Search on type
var result;
$('#search').on('keyup', function() {
result = '';
// Search h2 caontaining search term
$('h2:contains("' + $('#search').val() + '")').each(function(index) {
result += '<li>' + $(this).text() + '</li>';
});
// Show results
$('#searchResults').html('<ul>' + result + '</ul>');
});
#searchResults {
background: yellow;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
