Materialize dropdown doesn't work

For anyone having similar issue: I've got a similar problem because I was using jQuery 3.x beta. Switched to 2.2.2 and now it's fine. Seems like some changes in animations mechanisms.

Hope this helps somebody.

You can set the constraint_width = true or simply initialize dropdown without passing any json object.

$('.dropdown-button').dropdown({
           inDuration: 300,
           outDuration: 225,
           constrain_width: true, 
           hover: false, 
           gutter: 0, 
           belowOrigin: false 
           }
      );

Or you may initialize the dropdown with its defaults(by the way, json object provided above is the default dropdown value).

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