I want to give ability to admin to active or deactive a module for each store.

at previous magento version this option was exist under store -> configuration -> advanced -> advanced menue and we could enable or disable a module per store , but from magento 2.2 this option has been removed and no longer avalable.

according this link for this purpose we have to do some setting manually in our module .

I want to make setting in my module that admin can see the list of stores and by selecting them to enable or disable a module . for example admin wants to enable module be active for store A and B , and deactive for store C .

the list of stores should be dynamic and reads from database and shouldn't be hard code.

I don't have any idea how can I do it .Someone can help me figure out how I can do it ? If you could please point this out, I would be really grateful .

You can create admin filed using system.xml, then use that field to whatever the location..

For example..

By using etc/system.xml

 <group id="general" translate="label" type="text" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
 <label>General Configuration</label>
 <field id="enable" translate="label" type="select" sortOrder="1" showInDefault="1" showInWebsite="1" showInStore="1">
 <label>Module Enable</label>
 <source_model>MagentoConfigModelConfigSourceYesno</source_model>
 </field>
 </group>

Then get this value in helper class

/*
 * @return bool
 */
public function isEnabled($scope = ScopeInterface::SCOPE_STORE)

 return (bool) $this->scopeConfig->isSetFlag(
 'additional_registration_fields/general/enable',
 $scope
 );

then in block you can use as

public function isEnabled()

 return $this->helperData->isEnabled();

& final check on view files of frontend:

<?php if ($block->isEnabled()) : ?>
 // code here if module is enabled for current storeview
<?php endif; ?>
