Select as Dropdown: add function to recreate options

[djhi]

Use case: localization

In my app (using Meteor), users can change current language. Thanks to Meteor templating engine, the select options update accordingly. But not the materialize dropdown which has already been created.

I need either a function to destroy the materialize_select behaviour (and remove dropdown) or a function to force it to recreate the dropdown.

Thanks !
