  • options An associative array of value=>labels to generate options for.
  • idPrefix Prefix for generated ID attributes.

Options format

The options option can take a variety of data format depending on the complexity of HTML you want generated.

You can generate simple options using a basic associative array:

'options' => ['elk' => 'Elk', 'beaver' => 'Beaver']

If you need to define additional attributes on your option elements you can use the complex form for options:

'options' => [
  ['value' => 'elk', 'text' => 'Elk', 'data-foo' => 'bar'],
]

This form requires that both the value and text keys be defined. If either is not set options will not be generated correctly.
