Drop-down list / List box

Drop-down lists will be used to display entries in list format.

The list field works like a selection list, but displays the entries open in the browser.

Both input controls belong to the basic controls and can be found there under "Lists". The selection can be saved with a corresponding button if a data field is linked to the element.

The entries in comboboxes and Listboxes can come from different data sources.

The elements can be found in the "Applications" module in the "Elements" area. A new element can be created by positioning it on the workspace from here using drag & drop.

Further information on creating elements can be found here.

The properties dialog of a selection list or listbox opens automatically when a new element is created. The properties dialog of an existing element can be opened by double-clicking on the element on the workspace, via the context menu "Properties" or via the main menu "Edit / Properties" if the element is selected on the workspace.

The drop-down list becomes a mandatory field.

Entries - Values from applications

This option uses data from the data groups of applications as entries. The data can also be filtered if only an extract of it is to be selectable in the list.

You also have the option of specifying a saved value as the source and using a different value from the same data record for the entry in the list (e.g. user ID as the saved value, user name as the display value in the list).

Application, Data group, Stored value

Select the application, data group and data field whose saved value is to be used as an entry.

Filter

Opens a dialog in which a filter can be defined.

Data Picker

The data picker is used to transfer the values selected in the selection list to input elements that are located on the same page. For example, if you have selected the "User" system application as the data source, you can transfer the user name to any field on your application page.

Click on "Data Picker" to open a dialog in which you can make the data assignment.
