This plugin fixes the widget areas on WordPress widgets page on the admin backend so they always remain in view when scrolling up/down.
It will greatly reduce the time and effort in having to hold widgets and drag a long distance up and down.
Set to work from 481px and above i.e., only when the widget areas appear on the right side, in a column.
If you do not wish to use the plugin and want to temporarily achieve the same sticky widgets, bring up your browser’s dev tools and add this CSS to the widgets page:
<pre><code>@media only screen and (min-width: 481px) {

 .widget-liquid-right {
 position: -webkit-sticky;
 position: sticky;
 top: 42px;
 }

}
</code></pre>

Admin Sticky Widget Areas

I love the idea of this plugin, but it feels like it needs a bit of polish. While position: sticky; is enticing, the scrolling behavior is not great when one or more widgets are expanded so that the widget(s) you are editing are taller than one screen. In that case, you can't scroll to see the active widget areas until you've scrolled to the bottom of the page. Using some kind of JS behavior more similar to how the default core "Edit Post" page sidebar works would make this a no-brainer 5-star plugin, and I look forward to updating my rating!

Fabulous idea. Needs polish to be useful.

A simple plugin bat it solves a problem.

The <a href="https://wpsticky.com/" rel="nofollow ugc">WP Sticky</a> Menu (or Sticky Header) On Scroll plugin allows you to make any element on your pages “sticky” as soon as it hits the top of the page when you scroll down. Although this is commonly used to keep menus at the top of your page to create floating menus, the plugin allows you to make any element sticky. Make a sticky header, stick menu, sticky widget (fixed widget), sticky logo, sticky call to action or a floating menu.
You just need to know how to pick the right selector for the element you want to make sticky, and you need to be sure it’s a unique selector. Sometimes a simple selector like “nav”, “#main-menu”, “.menu-main-menu-1” is enough. Other times you will have to be more detailed and use a more specific selector such as “header > ul:first-child” or “nav.top .menu-header ul.main”. If you don’t like messing with any code check out out the visual element picker in <a href="https://wpsticky.com/" rel="nofollow ugc">WP Sticky PRO</a>.
<h4>Features</h4>
<ul>
<li>Any element can stick: although common use is for navigation menus, or header the plugin will let you pick any unique element with a name, class or ID to stick at the top of the page once you scroll past it. Use it for sticky widget, sticky sidebar, sticky header, sticky menu, sticky header, sticky call-to-action box, sticky banner ad, etc. Need to make <a href="https://wpsticky.com/" rel="nofollow ugc">multiple elements sticky</a>? Check out WP Sticky PRO.</li>
<li>Positioning from top: optionally, you can add any amount of space between the sticky element and the top of the page, so that the element is not always stuck at the “ceiling” of the page.</li>
<li>Enable for certain screen sizes only: optionally, you can set a minimum and/or maximum screen size where the stickiness should work. This can be handy if you have a responsive site and you don’t want your element to be sticky on smaller screens, for example.</li>
<li>Enable only on some pages: sometimes you don’t want the element to be sticky on the entire site. <a href="https://wpsticky.com/" rel="nofollow ugc">WP Sticky PRO</a> gives you the option to pick posts, pages, categories, tags and CPTs where you don’t want the element to be sticky.</li>
<li>Push-up element: optionally, you can pick any other element lower on the page that will push the sticky element up again (for example a sidebar widget).</li>
<li>Admin Bar aware: checks if the current user has an Admin Toolbar at the top of the page. If it has, the sticky element will not obscure it (or be obscured by it).</li>
<li>Z-index: in case there are other elements on the page that obscure or peek through your sticky element, you can add a Z-index easily.</li>
<li>Legacy Mode: in 2.0, a new method of making things sticky was introduced. In Legacy Mode, the old method will be used. See FAQ for details.</li>
<li>Dynamic Mode: some issues that frequently appear in responsive themes have been address by adding a Dynamic Mode (Legacy Mode only). See FAQ for details.</li>
<li>Debug Mode: find out possible reasons why your element doesn’t stick by switching on Debug Mode, and error messages will appear in your browser’s console.</li>
