Drop Down List Description

This is the Need4Viz Wiki page for the Drop Down List from Navigation Elements.

Since Need4Viz 2025.2.10

• Display a drop-down list to be able to dynamically filter elements of the report.
• Ability to manage grouping of values from the list and assign different input controls depending on the level selected.

• Dimension 1 : Elements of the list (or elements of the group in case of hierarchy list)
• Dimension 2 : [optional] Elements of the list (in case of hierarchy list)

• [Groups] Elements sorted by : [optional] Dimension to sort the elements of group/list
• [Groups] Elements sorted by : [optional] Dimension to sort the elements of list

• Build the Simple list navigation component
• Create an Input Control (simple values kind, with a uniq name in all the document) and affect it to the blocs of your report (except the navigation component)
• Declare the Control for the list [and the group], through the global settings of the custom element, to affect the selected values.

• Do not use the Webi linking element to link this element with another element. Use only the Input Control settings to set the interaction.

• The control (for list/group) can be an Input Control or a Webi Variable.
• When a group is defined, depending on the settings (group selectable, link list/group selection…), the behaviour of the affectation (Input control or variable) will change.

You can find instructions here to access the settings for Need4Viz graphics: Format custom display.

For the simple value list, the available parameters are as follows:

Extended parameters

• Global
  • Title of the chart : this common parameter is described here → Chart title
  • Background color : This setting allows you to choose the type of colorization for the background of the graph. Several styles and colors are available.

• Options
  • List option : This setting allows you to add the value 'all values' at the top of the list or not. It also allows you to choose a label for 'all values' and to make the 'all values' value selectable or not. You can also set here the font of the items of the list and the background color of the list.
  • Option group : This setting makes the group selectable or not. You can alse set here the font of the items of the group in the list.
  • Custom list : You can set and define here a custom list to display in the list instead of the giving parameter.

• Selection
  • Style : Define here the style of the selected value (by default the style of the items in the list is applied).

• Controls
  • List item control : This setting allows you to assign a control to feed with the selected value of the list. It can be an input control or a Webi variable. A reset default value can also be set for Webi variable control.
  • Group item control : This setting allows you to assign a control to feed with the selected value of the group. It can be an input control or a Webi variable. You can also choose to link list/group controls when selecting a list item.
  • Apply on report : Choose here to apply the selection immediately or later (in this case do not omit to use a button Apply Filter to apply all filters).
  • Input Controls reset option : This setting allows you to choose the input controls that must be reset or not. If “All except specified” is set and no list is feeded, all report input controls will be reset when selection is done. You can also choose the type of action to perform on the input control(s): Reset or send “All values” (this allows the input control to use a default value on reset ).
  • Variables reset option : This setting allows you to reset your Webi variables during the selection (use “;” separator). A reset default value can also be defined (default value is #N4V_ALL).
  • Drill levels storage : This parameter makes it possible to delete from the cache of the user's browser, all the values of the last drill levels operated on the current report. All drillable components of the current report will therefore be reset to their main level.
