1. Dynamic list definition

A dynamic list is a list of values which subsequent elements are not permanently defined (as  a standard list of values), but determined by a suitable component.

Thanks to this, it is possible to gain access to, among others lists with values from an internal or external database.

Dynamic list sample

2. Dynamic list selecting

In PWE from the bar on the left side you can choose „Dynamic list” and move to any place on the form..

After double-clicking the newly created field, the configuration window will appear. Add a new process variable by clicking the green plus button (see below).

To select the appropriate component for the dynamic list, press the gear button with the arrow in the process variable configuration. In the screen that showed up, we choose the component we are interested in.

After selecting the component, it should be configured by setting the appropriate parameters and values mapping.

3. Component parameters

You can read about the parameters of the dynamic list on a separate page: Component parameters.

4. Value mapping

Value mapping is responsible for what elements of the dynamic list will be displayed and where they will be assigned in case of selection.

• Name - Name (the most common identifier) of the element downloaded from the component. Depending on the component, you can select it from the list or fill it on your own (detailed information are in the documentation for the specific component).
• Description - Description of the displayed element configured in the component. It is only for information during configuration.
• Process variable - Process variable to which the element value will be saved.
• Display name - The name under which the selected item will be displayed when expanding the dynamic list.
• Hidden - Hides the item while expanding the dynamic list (but still assigns a value to the variable when selected).
• Verify - Checks whether the given parameter value exists, if the user has completed the value itself.

5. Dynamic list editing

To edit a dynamic list, double-click on the datachoser element and then on the pencil icon. We get access to the same configuration as creating a dynamic list.
