function template_preprocess_select

Prepares variables for select element templates.

Default template: select.html.twig.

It is possible to group options together; to do this, change the format of the #options property to an associative array in which the keys are group labels, and the values are associative arrays in the normal #options format.

Parameters

$variables: An associative array containing:

• element: An associative array containing the properties of the element. Properties used: #title, #value, #options, #description, #extra, #multiple, #required, #name, #attributes, #size, #sort_options, #sort_start.
