Admin Collapse Subpages

Works without any issues for me in WordPress 6.4.4

I added some custom backend CSS (via the Code Snippets plugin) to style it with the eye/visibility icons and semi opaque descriptions for a more intuitive user-experience:

add_action('admin_head', 'custom_admin_css');
function custom_admin_css() {
  echo '<style>
	/*-------/ Plugin: Admin Collapse Subpages /-------*/
	body.wp-admin .column-primary .expand_link a:before {content: "f530"; opacity: 0.85;}
	body.wp-admin .column-primary .expand_link a.minus:before {content: "f177"; opacity: 0.3;}
	body.wp-admin .column-primary .expand_link a:after {
    	content: "Subpages hidden";
		position: absolute;
		font-family: sans-serif;
		font-size: 10px;
		height: 12px;
		opacity: 0.85;
		margin: 3px 0 0 5px;}
	body.wp-admin .column-primary .expand_link a.minus:after {content: "Click to hide subpages"; opacity: 0.3;}
	body.wp-admin .column-primary .expand_link a:hover:before,body.wp-admin .column-primary .expand_link a:hover:after {opacity: 1;}
	body.wp-admin .column-primary .expand_link a.minus:hover:before,body.wp-admin .column-primary .expand_link a.minus:hover:after {opacity: 0.6;}
  </style>';
}

I'm using this plugin and it's a godsend. Just install and view your Pages section in your backend Administration area. You can expand/collapse all, or click on individual page headings and the usual menu of all the sub-pages below expand. I'm using v6.0 +1

Thanks a lot !

I am managing taxonomy 'brand' and page with this plugin. for taxonomy terms,I added a new line JS file,the code like:jQuery('.acs-hier.taxonomy-brand .actions').append(catLinks); also I change some Style on parent element or son element,such as background-color,border,font-size,display:none,etc the code like: jQuery(this).addClass('has-sub') little change, more effect. save much time for me. thanks!

I'm web developer and you helped me to manage more than 350 pages on my client website very easily, thank you very much and I want to help you by translating this supplement to Arabic if you want :) And what about Donation button? I want to support you with small amount ;)

Nice and simple to use.

It's even better in combination with Simple Page Ordering, and works fine, despite both plugins acting on the same interface. Thank you :)

Thank Author create this plugin! My client sites have a lot of subpages and they need kind of this plugin to collapse or expand all subpages.

It does the job just great — helps organize endless subpages. Thanks for the plugin!
