The countModules function can be used within a template to determine the number of Modules enabled in a given Module position. This is commonly used to include Modules in a certain position only if at least one Module is enabled for that position. This prevents empty regions from being defined in the template output.

The ''countModules'' method can be used within a template to determine the number of modules enabled in a given module position. This is commonly used to include HTML around modules in a certain position only if at least one module is enabled for that position. This prevents empty regions from being defined in the template output and is a technique sometimes referred to as "collapsing columns".

The countModules method can be used within a template to determine the number of modules enabled in a given module position. This is commonly used to include HTML around modules in a certain position only if at least one module is enabled for that position. This prevents empty regions from being defined in the template output and is a technique sometimes referred to as "collapsing columns".

For example, the following code includes modules in the user1 position only if one or more modules are enabled for that position. 

<?php if ($this->countModules( 'user1' )) : ?>
  <div class="user1">
    <jdoc:include type="modules" name="user1" style="rounded" />
  </div>
<?php endif; ?>
