I remember that it's possible, you need to set the correct lightbox options I believe.

Have a look at https://www.jacklmoore.com/colorbox/

or maybe you need to store the 'parent' state in a var or something like that.

Thank @jerome, 

I spent some time on the lightbox options, but I didn't find any useful for my problem.

Does anyone have any solutions for me?

It's a question about JS experience.

Look at jQuery API.

I read a lot about jquery colorbox.

Here is the only way to do.

The first colorbox instance should to load in an iframe. In this iframe we can load another colorbox.

My issue now is how can I load an ajax view in an iframe ? I am using  ajax view to create entity through a lightbox. 

elgg_register_menu_item('title', [

      'is_trusted' => true,

      'name' => 'addbusinessdirectory',

      'text' => "Add an entity",

      'title' => elgg_echo('add:object:pessekcompany:title'),

      'icon' => 'plus', 

      'link_class' => ['elgg-button', 'elgg-button-action', 'mrs', 'elgg-lightbox'],

      'href' => elgg_http_add_url_query_elements('ajax/view/pessek_company/add', [

                'guid' => $param1,

                 'container_guid' => $param2,

      ]),

      'data-colorbox-opts' => json_encode([

                'maxHeight' => '85%',

                'maxWidth' => '90%', 

                'width' => '60%',

                'iframe' => true,

      ]),

]);

Does anyone have any solutions for me?

Hello to everyone.
Does anyone have any solutions for me?
Open 'Elgg Lightbox' From another 'Elgg Lightbox' without closing the parent.

Since you are struggling with this question for some time and since the experts have not provided a solution you can try to include in the content of the parent lightbox a hidden div with absolute position, and visible button or link . Then, click the button to unhide the div.
