# Binding data model context To easiest the readability and maintainability of the code, and to shorten in XPath paths, some components can works as a relative xpath context for the contained ZK components. When a container type object is associated with a data model element, binds on child components that do not specify a data source are understood as parent container relative XPaths. The components that can act as context data model implement the es.caib.zkib.BindContext interface. Currently, grid, lisbox, row and form components. Due to implementation constraints, the listiem object does not implement the aforementioned interface. The simplest of those components is the Form object (which derives from Vbox). For context associations, the attribute to be used is called datapath, as shown in the following example: ```western
