Mistakes in the sample code in the dropdown documentation

[seita1996]

There is an error in the sample code for the drop-down document.

Current Behavior

I was not able to get the dropdown to work correctly after applying this code.

$('.dropdown-trigger').dropdown();

https://materializecss.com/dropdown.html

Possible Solution

You need to wait for the HTML to load as shown below as well as the other parts.

$(document).ready(function(){
    $('.dropdown-trigger').dropdown();
});

May I submit a PR for the document?
