Render a Collection of Select Options

Renders a set of HTML `<option>` elements, representing possible choices for a `<select>` element. This tag can be used multiple times within a single `<html:select>` element, either in conjunction with or instead of one or more `<html:option>` or `<html:optionsCollection>` elements.

This tag operates in one of two major modes, depending on whether or not the `collection` attribute is specified. If the `collection` attribute is included, the following rules apply:

- The collection attribute is interpreted as the name of a JSP bean, in some scope, that itself represents a collection of individual beans, one per option value to be rendered.
- The property attribute is interpreted as the name of a property of the individual beans included in the collection, and is used to retrieve the value that will be returned to the server if this option is selected.
- The labelProperty attribute is interpreted as the name of a property of the individual beans included in the collection, and is used to retrieve the label that will be displayed to the user for this option. If the `labelProperty` attribute is not specified, the property named by the `property` attribute will be used to select both the value returned to the server and the label displayed to the user for this option.

If the `collection` attribute is not specified, the rules described in the remainder of this section apply.

The collection of values actually selected depends on the presence or absence of the `name` and `property` attributes. The following combinations are allowed:

- Only `name` is specified - The value of this attribute is the name of a JSP bean in some scope that is the collection.
- Only `property` is specified - The value of this attribute is the name of a property of the ActionForm bean associated with our form, which will return the collection.
- Both `name` and `property` are specified - The value of the `name` attribute identifies a JSP bean in some scope. The value of the `property` attribute is the name of some property of that bean which will return the collection.

The collection of labels displayed to the user can be the same as the option values themselves, or can be different, depending on the presence or absence of the `labelName` and `labelProperty` attributes. If this feature is used, the collection of labels must contain the same number of elements as the corresponding collection of values. The following combinations are allowed:

- Neither `labelName` nor `labelProperty` is specified - The labels will be the same as the option values themselves.
- Only `labelName` is specified - The value of this attribute is the name of a JSP bean in some scope that is the collection.
- Only `labelProperty` is specified - The value of this attribute is the name of a property of the ActionForm bean associated with our form, which will return the collection.
- Both `labelName` and `labelProperty` are specified - The value of the `labelName` attribute identifies a JSP bean in some scope. The value of the `labelProperty` attribute is the name of some property of that bean which will return the collection.

Note that this tag does not support a `styleId` attribute, as it would have to apply the value to all the `option` elements created by this element, which would mean that more than one `id` element might have the same value, which the HTML specification says is illegal.
