Selection Type

The Selection Type property of the Select field lets you define if the field has Single Choice or Multiple Choices.

Single Choice: This will let the user select only one option from the given choices on the entry page. In this case, you can render the choices in either Radio or Dropdown options.
Multiple Choices: This will let the user select multiple options from the given choices on the entry page. In this case, you can render the choices in either Checkbox or Dropdown options. For this option, you can set the minimum and the maximum number of choices that the user can select.
