# Menu selection input

A menu selection input is used to select a key field value from a machine task or a table. Menu selection inputs take up less space than list selection inputs, but are less practical for large data sources with lots of information in each record.

Menu selection inputs have the following properties:

* **Target Variable**\
   The name of the new variable(s) in which to store the selected value. The data that will be stored in the varibale is the value frpm the seleced variable in "Field to select".
* **Table Variable**\
   Choose the table that will be the data source in the list.
* **Prompt**\
   The label displayed at the top of the list.
* **Row Text**\
   Enter text and variables that should be displayd in the list. Use {} to get a list of available variables from the source table.
* **Default Value**\
   Enter a default value based on the values of the variable entered in *Field to Select*.
* **Field to Select**\
   The target variable will contain the value of this field.
* **Show Empty Option**\
   The list will be empty when the user enter the user step.
* **Text of Empty Option**\
   Enter a text for the empty option (optional).
* **Allow Empty Option Selection**\
   If set to **True**, the operator is allowed to move forward in the workflow without entering anything into the text field.
