| jbe/bsw@0 | 26 This functions creates a web form, which encloses the content created by the given 'content' function. When a 'record' is given, ui.field.* helper functions will be able to automatically determine field values by using the given record. If 'read_only' is set to true, then a call of ui.submit{...} will be ignored, and ui.field.* helper functions will behave differently. |
