  1. Choice field – it is the most universal field. You can define your own data set or use the existing one. In addition it is divided into three subtypes:
  • Dropdown -> the selection of one value from the drop-down menu
  • Pop-up search window -> an additional pop-up window appears, where you can select several options
  • Autocomplete -> a text field that dynamically suggests answers depending on the given characters
  1. Person or group – allows you to search and select people, domain groups or SharePoint groups.
  2. Date and time – allows you to present and edit date and time
  3. Yes/No choice – used to select the Yes/No value. The value of this form field is set by a checkbox on the instance.
  4. Choice tree – allows you to display the value in the form of a three and select one of the available options.

When adding the picker fields they must be configured in the Advanced configuration button menu. Otherwise, when you try to save you will receive a message:

Business case

A Car reservation workflow has been configured. At the first step select:

  1. Driver – a Peron or group field
  2. Start and end date of use – a Date and time field
  3. Car – a Choice field

A car driver can be selected by entering a fragment of a user name. If the entered value is unique – the system will select the user.
