Editable Dropdown Parameters
Some parameters provide dropdown menus, also known as enum parameters, that allow users to select a value from a predefined list of options.
These parameters simplify configuration by presenting common values directly in the user interface.
Dropdown Parameters
Standard dropdown parameters contain a fixed list of predefined options.
Users can select one of the available values from the list.
This type of parameter is commonly used when only a limited number of valid values exist, such as:
mode selections
device configurations
predefined states
Editable Dropdowns
Some dropdown parameters are editable.
In this case, the dropdown still provides a list of predefined options, but users can also enter custom values or modify the available options.
This allows users to adapt the dropdown list to the needs of a specific project.
Editing Dropdown Entries
The list of entries for an editable dropdown can be modified through the Parameter Settings.
To edit the dropdown entries:
Right-click the parameter
Select Parameter Settings
Open the dropdown editor
Within the editor, new entries can be added using the + icon.
Each entry contains two values:
Key
The label displayed in the dropdown menu
Value
The internal value used by the system or programming logic
The Key defines what the user sees in the interface, while the Value can be used by workflows, scripts, or other systems.
Using Values in Programming
When working with dropdown parameters in programming systems, it is possible to reference either:
the Value defined in the dropdown entry
the index position of the entry in the list
Using the Value is generally recommended.
If the index is used instead, changing the order of the entries may break existing logic.
Defining explicit values ensures that the parameter remains stable even if the list order changes.
Reordering Entries
Entries can be reordered easily using drag and drop inside the dropdown editor.
This allows users to organize the dropdown list in a logical order without needing to recreate the entries.
