A choice field provides several predefined options to choose from, and only one option can be selected.

In the SimpleOne interface, choice fields are displayed as a drop-down lists, as in the example below:

There are two ways to define a set of choices for the drop-down lists:

  • by inheriting values from a parent table (if current table is a child to another one)
  • by creating a set of records for this field in the Choice Options dictionary
  • by defining a source table and its columns in the Type Specification tab.

In the second case, you may need to create a different set of choices if the column is inherited and has predefined options. See Defining an override for choice fields to learn more.

In the third case, the available options are taken from a particular column of a source table. In the example below, the choice table Role contains a column Name and some records where Name is not empty. The choice options will be values of the Name column in this table.

Sources for choice options

There are three ways to define a set of choices for the drop-down lists:

  • by inheriting values from a parent table (if the current table is a child of another one).
  • by creating a set of records for this field in the Choice Options (sys_choice) table.
  • by defining a source table and its column in the Type Specification tab.

In the second case, you may need to create a different set of choices if the column is inherited and has predefined options. See Column Override to learn more.

In the third case, the available options are taken from a particular column of a source table. In the example below, the choice table Role contains a column Name and some records where Name is not empty. The choice options will be values of the Name column in this table.
