In Magento, you can order modules from an online store to extend the functionality of your website. Here are the steps to order a module from an online store in Magento:
Log into the Magento admin panel.
Go to System > Magento Connect > Magento Connect Manager.
In the Magento Connect Manager, you can search for the module you want to install by entering the module name in the “Search” field.
Select the module you want to order and click on the “Install” button.
Review the extension license agreement and then click on the “Proceed” button.
Wait for the installation process to complete.
Once the installation is complete, go to System > Configuration > Advanced > Advanced and make sure the module is enabled.
You can also go to System > Cache Management and refresh the cache.
Note: If you’re using Magento 2, you should check the documentation for more details on how to order a module from an online store.
Also, you can use Magento Marketplace as an official marketplace for Magento extensions. It’s a one-stop shop for purchasing and installing Magento extensions.
