Angular 8 cannot get child panel to scroll properly to top of screen

I have a parent component that has 4 child components inside of it, each of them a primeNg panel with a form inside of them. The first 3 panels are expanded at all times(the collapse and expand icons are set to empty strings) and the last one is collapsed on load. On the last panel, I have a button that allows you to "Edit" the information which appears inside it and expands the panel.
What I would like is for this 4th panel to then get pulled to the top of the screen. However what actually happens is the panel expands and the scroll bar moves up, but the panel itself stays put.
I have tried several different options to get this working using various combinations of scrollTop, offsetTop, scrollIntoView, etc but nothing has worked. The scrollbar moves but the content does not, it stays where it was.
I even tried to set the id to an element half way down the form on the last panel and then used scrollIntoView: {block: 'center'} as an option...still nothing, same thing, it scrolls the scrollbar but not the content.
Can someone help me out with this and let me know what I am doing wrong?
in parent component:
<p-panel1></p-panel1>
<p-panel2></p-panel2>
<p-panel3></p-panel3>
<p-panel4 id='scrollToHere'></p-panel4> <---I want to scroll p-panel4 to top of the window
when the edit button is clicked
UPDATE:
Got it fixed by using setTimeout(document.getElementById('scrollToHere').scrollIntoView({behavior: 'smooth', block: 'start'}),0)
gotta be one of those weird DOM things where it tried to scroll before the panel was expanded...will try and change it to onAfterToggle but not sure if that will work because I am not using the icons and using a button to do it.

#Matte the scroll into view should work. But it seems that the scroll into view is triggered before you contents are expanded so try with some delay. And there should be more page content below your last panel if there is nothing and it is the last thing on page then the page would not scroll to the top of the height is smaller then the screen

Transitioning a button into a modal

I'm attempting to expand and transition a button into a modal that's 60% of the height and width of the window when it is clicked. Here's a CodePen of my work so far: http://codepen.io/anon/pen/WbNONa. The problem I'm having is that the position property can't be transitioned. Both the button and the modal (which is underneath the button) are absolutely positioned inside the button wrapper to make both elements look like one element. When the button is clicked, the modal should expand to a fixed position on top of the overlay.
The issue is that the positioning immediately changes from absolute to fixed, so the modal just looks like it's contracting from the full window size. If you delete the position: fixed property on the #btn-content.active class, you can see what I'm essentially trying to do. How can I emulate the transition of the position property? If that's not possible, how can I have the modal transition to a height and width that are relative to the size of the window? Thank you kindly for your time.

Making jQuery Popbox visible outside of its parent

Using the jQuery popbox library (http://gristmill.github.io/jquery-popbox/index.html) I encountered the following problem:
I have a huge div which has it's overflow set to auto. It is actually a tournament grid displaying a lot of matches to be played. Each match (separate divs) has a small info icon and upon clicking, I'm using the Popbox to display additional information in the window that comes up.
This is all working correctly, however, whenever I press the info icon on a div that's close to the bottom side or the left side of the parent div which has it's overflow set to auto, part of the popbox window is not visible as it ends up outside of the parent div. I'm looking for a user-friendly way to solve this issues.
Setting the parent's div overflow to visible is not an option as I need the scroll bars to appear if it gets too large. It would be nice though if I could make the Popbox window go outside of the parent div and be completely visible.
The other idea that I can think of right now is to set special classes to the info icons close to the edges and adjust the popbox window to the right/top so it is visible in the parent div regardless of its overflow.

I suggest you to use some special classes and make the popover "pop" on top/right.
You can see an example here: http://getbootstrap.com/javascript/#popovers
If you want to use Bootstrap you can make a custom build here: http://getbootstrap.com/customize/?id=6493526

Popup window to always appear fixed to top edge BUT scrolls with entire page if content larger than screen height?

Let me try and make sense. I have a search page that returns lots of search results just like Google. Each of those search results have a trigger (via an icon using onmouseover) to access more info in a popup window that pops up to the right of all the search results, just like google. Here is what I want from the popup window:
No matter if I am looking at the first search result at the top of the page, or the last search result way down at the bottom of the page, I want the popup window to align itself with the top edge of the screen, regardless of where I am vertically on the page (similar to fixed)
BUT, if the popup window happens to contain more data then the vertical screen height allows, instead of the popup window creating scrollbars internally, I want the popup window to scroll right along with everything else on the page (similar to absolute)
The problem is that fixed chops off data that goes below the bottom of the visible browser window height making it inaccesible without internal scrollbars. With absolute, the popup scrolls along with all the other stuff on the page which is great and what I want, but it always appears at the very top of the page, even when I am at the bottom of the page, making it invisible to the user if the results list is very long.
Its like I am trying to combine the two methods in a way. So to summarize:
When I trigger a popup via onmouseover, the popup window should affix itself to top edge always no matter where I am vertically, but if its content is vertically taller than the screen allows, I should be able to scroll the entire page down to see the rest of it. I should not have to use internal scrollbars within the popup window like fixed.
Is this possible and how should I go about it? Thanks!

You're going to need JavaScript.
First, make set the popup divs to position: absolute. This will act like fixed in that it can go anywhere on the page easily through left and top, but it still scrolls with the page.
On link hover, make the JS detect the browser's scroll position (through window.offsetY or $(window).scrollTop() in jQuery). Apply this offset to the popup:
$('.link').on('click', function () {
$('.preview').css('top', $(window).scrollTop());
});
Remember also to tweak the other CSS properties of the popup to suit your needs - however, most of that can be done in CSS; the only JS you really need is for the top property.

Position a modal window

I have a web page with a long list of products. Next to each product there is a link to view details about the product. The details are displayed in a modal window.
The goal is to get the same behavior you can experience when looking at pictures on facebook:
the modal window is displayed on ~50px from the top
if the modal window height is greater than the viewport height than the user can scroll down (the scroll bar is now working toward the modal window NOT the page which is in the background)
when the modal window is closed the user is at the same position in the list of products as it was before it opened the modal window.
I am almost there, expect for the last requirement. The way I have implemented this is by simply opening the modal window with JS and then use:
var winH = window.pageYOffset + 50
$('#show_message_overlay').css('top', winH+"px");
to position the modal window.
Feel free to suggest a better approach.
Thanks for any help.

The solution turns out to be more complex than I thought:
create the modal window inside a div that has the same width and height as the body element
store the scroll offset before showing the modal window
show the modal window with JS (note that the modal window div now cover the all viewport)
with JS set the scroll css value of the body element to hidden (this will remove the scroll bars from the page)
set the overflow value of the element that contains the modal window to scroll (this can be done in the css file), this will now create scroll bars if the model window is bigger than the viewport
ENJOY your awesome modal window and scroller!
once the window is closed reset the scroll offsets using JS

Isaac Schlueter over at FooHack.com has put together a great example of a CSS Modal Dialog Box that exactly fits your requirements:
http://foohack.com/2007/11/css-modal-dialog-that-works-right/
From the article:
Interaction with the contents of the parent window should be impossible until the modal is dealt with. Scroll-mouse should not scroll the background page, clicking should not click the background page, tabbing should not get you there, etc.
When you dismiss the modal, the parent window should be exactly how you left it.
The parent window should be dimmed, or there should be some other indicator that it is currently not available for interaction. This has the corollary effect of making the modal “pop” a bit more.
In a web page, a modal should be constrained within the viewport. Opening a new window just to show a dialog box is ugly as a bucket of slugs.
The modal should be placed consistently. If it is not movable, then it should be centered vertically and horizontally. This positioning should be consistent if the parent window is resized or moved.
The modal should be smaller than the parent window. If the viewport is resized smaller than the modal, then scrollbars should appear that allow the user to see the rest of the modal.

If the page's scroll bar is being altered because of user's scrolling on the modal window, you can save the page scroll position while opening the modal bar and than on closing the modal window you can set the page scroll position to the position you have saved.
