| This script enables collapsible fieldsets. Fieldsets must be enclosed in a     |
| <fieldset></fieldset> tag, with the header in a <legend></legend>. All content |
| must be enclosed in an unstyled <div></div>. To enable this feature, fieldsets |
| must have the "collapsible" property set "true" or "false"                     |
|                                                                                |
