How to add modules to the system in YII2 through the admin panel?

First, to develop and prepare all available modules. In the file main.php/main-local.php (or in another place of the alleged connection of the modules) and enter this:

$modules = require('/path/to/modules/file.php');
// continue
return [
 'modules' => array_merge($modules, [
 'user' => [
 'class' => common\modules\user\Module::className(),
],
]),
];

To create a label in the database, where are stored all the modules. Using CRUD to create a functionality to change the status of the modules. Next to the GridView to create a button, by pressing on which all active modules will generate the file '/path/to/modules/file.php' along the following lines:

return [
 'questions' => [
 'class' => common\modules\poll\questions\Module::className(),
],
 'answers' => [
 'class' => common\modules\poll\answers\Module::className(),
],
 'news' => [
 'class' => common\modules\news\Module::className(),
],
 'tags' => [
 'class' => common\modules\tags\Module::className(),
],
 'categories' => [
 'class' => common\modules\categories\Module::className(),
],
 'images' => [
 'class' => common\modules\images\Module::className(),
],
 'uploader' => [
 'class' => common\modules\uploader\Module::className(),
],
 'content' => [
 'class' => common\modules\content\Module::className(),
],
 'employees' => [
 'class' => common\modules\employees\Module::className(),
],
 'comments' => [
 'class' => common\modules\comments\Module::className(),
],
];

In principle, as it all. Only error here is not insure, because one module often works with others in pairs. For example, a free-standing modules, articles, blogs, news, weather - so Makar, can be mounted, but any Comments that are connected to other modules, probably without editing the code will not work.

the question is to be functional in order to not a competent user himself could take the module and attach it to the system through the admin panel, as well as in cms
