Repeatable form field type

Provides a modal with rows of formfields that you specify. As many options can be added as desired. Note this form field has a jQuery based javascript file as a dependency.

• name (mandatory) is the unique name of the parameter.
• type (mandatory) must be repeatable.
• label (mandatory) (translatable) is the descriptive title of the field.
• description description text for the form field. Displays at the top of the modal with the name as well as in the usual position in the form.
• default The default value for the form field if the field is left empty. Note this has to be a json string compatible with the contents of the form field.
• id id of the hidden form field. (the modal will have this id with an added suffix of "_modal" and the table within the modal will have this id with a suffix of "_modal_table").
• class class of the table.
• select (translatable) The text to show on the modal button.
• icon the icon to show on the select button (is prefixed with "icon-").
• maximum the maximum number of rows of fields allowed (by default 999 to be effectively infinite).

To create a form field you must first of all create a repeatable form field as usual.

<fields>

Within this you place open and close tag (if not already in one - if there is an existing fields tag for params etc. this is not needed.) and within this a tag.

<fieldset>

The fieldset tag MUST have a name the same as your repeatable field name with "_modal" appended to the end of it - it should also have the in the fieldset tag.

repeat="true"

Within this fieldset you then include the form fields that you wish to have repeating (as with any form field).
