When inserting a IO "station" to a configurator project, the configuration of the buscoupler offers a list of all available IO modules in a list view. This list should be structured. Several nodes like e.g. "Dig. Input" should offer the possibility to expand or collapse the sub list with available digital input modules. Buttons "expand all" and "collapse all" help to see the complete configuration, or to get fast to the sub list you want to reconfigure.
