#select_id(obj, sym, opt = {}) ⇒ Object

Display an input field to select an id. The user can enter an id or a name in the field and the node’s path is shown next to the input field. If the :class option is specified and the elements in this class are not too many, a select menu is shown instead (nodes in the menu are found using secure_write scope). ‘Sym’ is the field to select the id for (parent_id, …).
