Multiple selection

The multiple selection control is a list element in which several entries can be selected at once. For example, it is suitable for distribution lists, article groups etc. Multiple selection is available as an input and view element.

Multiple selection as an input element

Properties in the browser

Data source "Values from applications" / "User-defined values"

If you select the options "Values from applications" or "User-defined values" as data source in the properties of the multiple selection conytol, the browser element consists of two lists. All selectable entries are listed on the left, and all selected entries are listed on the right. The selected entries are stored in the linked data field when the page is saved, if a link to it has been configured.

The arrow buttons to the top right or left of the list titles can be used to move the currently selected entry from one list to the other. This can also be done by double-clicking on an entry. You can also select multiple entries by holding down the CTRL key.

The multiple selection can be configured to get its entries from, for example, an ID or GUID but display a different value from the same data group. For example, article numbers could be used as entries and the article description could be displayed instead.

Furthermore, you have the ability to set up a so-called selection filter, depicted by images that you can select freely, which will be shown above the entries. Clicking on an image activates the filter accordingly.

The values that have been entered with a multiple selection can be shown with the view elements “view multiple selection” and “view table”.

Users and groups

If you have selected the "Distributor selection" options as the data source in the properties of the multiple selection, the multiple selection can be used in the browser to select users, user groups and other objects from the "Users" module.

You can search for terms and filter the list of user objects. You can define which data should be used for the search in the schema manager. Activate the setting "Use in User manager search" for the corresponding attributes.

The selection filter - filter buttons above the user lists - allows you to restrict or expand the search to users, user groups, distribution lists, organizational units and roles, depending on whether the corresponding button is activated or deactivated.

When you save the data record, the GUIDs of the user objects will be saved to the linked data field. By clicking on "Create distribution list”, new distribution lists can be defined, provided that the setting "Create distribution list" is activated in the data source.

The structure of the User Manager will be shown here. Select where the new distribution list should be created and click on "Save".

Provide the new distribution list with a name and description here. The members of the distribution list can be defined underneath. Click on the button to the right to do that.

Select the desired member(s) here and click on "Save".

Go to the "Access permissions" tab.

You can define which users and/or objects from the User Manager will be allowed to change the recently created distribution list. Click on the button to the right to select the corresponding users. After saving, the new distribution list is entered in the "Users" module.

Click on to edit an existing distribution list.

Properties in the "Applications" module

When you create a multiple selection control in the Applications module, the Properties dialog opens automatically.

General

Here you can set the general properties of the multiple selection.

Title / Title from constant

A static title can be entered here. Alternatively, the title can be obtained from a language constant, which you can select here. Click here for more information about this topic.

Heading for 'non-selected entries' / Heading for 'selected entries'

The titles for both lists in the Multiple selection element can be defined here. A constant can be used here as well.

Input required

The element will be made into a mandatory field.

Invalid entries

Display stored values

If values from a multiple selection can be written to a data field, it is possible, e.g. through the export or import of an application, that the values are no longer valid. With this setting, these invalid stored values will be displayed instead of the current configured display values.

Delete when saving

If this option is selected, invalid values will be deleted from data fields in the current data record.

Search options

Initial search expression

This search expression will be automatically entered in the search field and will filter the "Available" list when the corresponding page is loaded. The maximum number of entries will be shown, if the character * is entered in the search field.

No search entry displays all entries

Displays all entries when the search field is empty.

Click "Next".

Data source

The source of the entries in the multiple selection is configured here.

Values from applications

With these settings the entries are created from the data of any application.

Application, Data group

Filter

Opens a dialog where a filter can be defined. The data will then be displayed in the multiple selection according to the filter criteria.

Saved value

Here, all data fields from the selected data group will be shown. You can define the field, whose values will be saved when the user selects an entry in the multiple selection. This gives you the ability, for example, to show names of employees in the multiple selection, but to save their ID number instead of the name.

Additional options

Maximum number of entries

The value limits the number of entries. With the value -1, all entries will be shown.

Users and groups

Instead of the data source option "Values from applications", the setting "Distributor selection" can also be chosen for the multiple selection. This means that the element can be used to select users, user groups and other objects in the "Users" module. Find out here how this multiple selection appears on the web and can be used there.
