Detailed Description

A container for HTMLFormFields that allows for multiple copies of the set of fields to be displayed to and entered by the user.

Recognized parameters, besides the general ones, include: fields - HTMLFormField descriptors for the subfields this cloner manages. The format is just like for the HTMLForm. A field with key 'delete' is special: it must have type = submit and will serve to delete the group of fields. required - If specified, at least one group of fields must be submitted. format - HTMLForm display format to use when displaying the subfields: 'table', 'div', or 'raw'. This is ignored when using OOUI. row-legend - If non-empty, each group of subfields will be enclosed in a fieldset. The value is the name of a message key to use as the legend. create-button-message - Message to use as the text of the button to add an additional group of fields. delete-button-message - Message to use as the text of automatically- generated 'delete' button. Ignored if 'delete' is included in 'fields'.

In the generated HTML, the subfields will be named along the lines of "clonerName[index][fieldname]", with ids "clonerId--index--fieldid". 'index' may be a number or an arbitrary string, and may likely change when the page is resubmitted. Cloners may be nested, resulting in field names along the lines of "cloner1Name[index1][cloner2Name][index2][fieldname]" and corresponding ids.

Use of cloner may result in submissions of the page that are not submissions of the HTMLForm, when non-JavaScript clients use the create or remove buttons.

The result is an array, with values being arrays mapping subfield names to their values. On non-HTMLForm-submission page loads, there may also be additional (string) keys present with other types of values.
