What is the best way to add elements to a multidimensional array in Smarty templates?

To add elements to a multidimensional array in Smarty templates, you can use the `{assign}` function along with the `append` modifier. This allows you to dynamically add elements to the array within the template itself. 

{assign var='multidimensionalArray' value=[]}
{assign var='element' value=['key' => 'value']}
{assign var='multidimensionalArray' value=$multidimensionalArray|array_merge:$element}
