I'm sure you really meant to use a single ? instead of screaming!!!!

To do this you can either remove the create module permissions for the user (probably not a good idea) or create a template override for administrator\components\com_cpanel\tmpl\cpanel\default.php

Thanks Brian, I don't mean to yell.

What it indicates I think requires average knowledge and my proposal is an option so that this box can be disabled by people without code knowledge, I have it like this:

1 - In the back end of Joomla, go to System > Templates > Administrator Templates.
2 - Click on "Atum Details and Files".
3 - Navigate to the tab "Create Overrides".
4 - In the "components" list, click on the "com_cpanel" folder, then on "cpanel". You should get a message that says "Override created in /administrator/templates/atum/html/com_cpanel/cpanel".
5 - In the "Editor" tab, click through the folders html > com_cpanel > cpanel > default.php
6 - Scroll down in the editor until you see the line "authorise('core.create', 'com_modules')) : ?>"
7 - Replace that line with: authorise('core.manage', 'com_modules') && in_array(8,$user->groups)) : ?>
8 - Save & Close.

That line originally checks if the logged in user has the permission to manage modules. The updated line checks that AND also if the user is a Super User, and only will show the "add module" box to Super Users.

But I see in forums that many people want to disable that box with a simple click.
It could not be an improvement with an option in the global configuration or in the template configuration.

As I have indicated, I have solved it, but several people want to disable that box and do not know or are afraid to edit code.

Thanks

Personally speaking I see it as an advanced customisation

Thanks for your suggestion, @Open2logic, it is surely worth being discussed. But please - could you change the title of your issue and use lower case without bangs?

Thinking about it, I think Brian is right, when a custom administration is prepared for a client, the developer is the one who hides that box by delivering a clean, empty or adapted interface.

I have reviewed forums where there is talk about how to hide the box and certainly all those interested are developers, however they do not think of code rewriting, it seems that their first natural option is to look for how to disable the box among the options (they are familiar with this method), which indicates that if everything that is shown in the panel can be hidden with a click, this box should also have the possibility to activate or deactivate it from an option, simply because it is the generic methodology.

A charm of the Joomla administration is its flexibility to be easily customized, simply with html modules and hyperlinks you can present a very attractive and practical administration with icons style App to an end client, pity of the exception of the "add modules" box to the board"

Your code proposal is also not suitable as the permissions for modules are the same for both site AND administrator modules. The ACL does not differientate between them.

Woow thanks Brian.

I think this will be resolved using the acl changes in #42467 by @chmst

Closing as PR #42467 merged.
