Column Filter Configuration

Options

Label

A descriptive label that will be shown in the dialog

Description

Some lines of description that will be shown for instance in the node description of the component exposing a dialog.

Parameter Name

Parameter identifier for external parameterization (e.g. batch execution). This will also be the name of the exported flow variable.

Type Filter

Allows to restrict the selectable columns to a certain type. Furthermore it is possible to hide columns that don't have a domain (for nominal and numeric columns). By default all columns are included.

Validation

Allows to specify the minimum number of columns the user has to select along with an error message that is displayed if the user fails to select enough columns.

Default Values

The columns that are selected by default.

Limit number of visible options

By default the filter component adjusts its height to display all possible choices without a scroll bar. If the setting is enabled, you will be able to limit the number of visible options in case you have too many of them.

Number of visible options

A number of options visible in the filter component without a vertical scroll bar. Changing this value will also affect the component's height. Notice that the height cannot be less than the overall height of the control buttons in the middle.
