select()
Builds and returns an HTML <select> element bound to a model object property. It automatically handles nested associations, labels, options, and error highlighting. You can provide a list of options as a query, array of objects, or simple array, and customize labels, HTML attributes, and encoding. It is especially useful for forms where a user must select a value from a predefined list that is related to a database model. Note: Pass any additional arguments like class, rel, and id, and the generated tag will also include those values as HTML attributes.

Use this argument to decide whether the output of the function should be encoded in order to prevent Cross Site Scripting (XSS) attacks. Set it to true to encode all relevant output for the specific HTML element in question (e.g. tag content, attribute values, and URLs). For HTML elements that have both tag content and attribute values you can set this argument to attributes to only encode attribute values and not tag content.
