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
Options
Text input options : These settings allow you to set the font, color and placeholder of the input text zone.
Button options : You can set here the validation button (color, label, font).
Controls
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 fed, 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 (set with #N4V_ALL content) during the selection (use “;” separator).
