Extends

Generator method used by `select()` to produce `<option />` and `<optgroup />` elements. Generally, this method should not need to be called directly, but through `select()`.

Parameters

array $list Either a flat key/value array of select menu options, or an array which contains key/value elements and/or elements where the keys are `<optgroup />` titles and the values are sub-arrays of key/value pairs representing nested `<option />` elements.
array $scope An array of options passed to the parent scope, including the currently selected value of the associated form element.

Returns

string Returns a string of `<option />` and (optionally) `<optgroup />` tags to be embedded in a select element.
