    - {block} block - The content within the select
  attributes:
  example: |
    include _htmlelements.pug
    +select({name:'my select'})
      +option({value:'a value','data-i18n':'a translation key',trigger:{affects:['some_attribute']}})
      +option({value:'value 2','data-i18n':'translation 2'})
      +option({value:'value 3'})
