If list‘s underlying array with data is modified externally, list must be rebuilt. Recalculates dynamic CSS rules for form and its childs. Unbinds all event listeners and removes all plugin instances attached. Manifests are single objects, without loop references and more or less scope independent. Pub/sub technique is good for broadcasting events, that may have out-of-app impact.Object returned after function, is nearly the same, but can contain empty string values (it means control under key-selector is valid).Allows different CSS rules to be applied over control’s container when conditions are met. There exists special key property, that is function. If returned value is not a promise, during form start.Set of repeated child form bound to an array of data are also supported.Moreover, array can consist of different-typed items – and list can render different child forms for them.
