Introduction

When creating forms, there is the ability of adding a field whose value can be selected from the data set. Regardless of whether the data set is weekdays, a user group or a predefined list – you can use picker fields.

  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.

In the next step, select the car which you want to reserve. Additionally, the field should be configured in such a way that by clicking on the plate number it is the ability to move to the given car card. To do this, go to the Designer Studio and select the appropriate field and click the “Advanced configuration” button.

Setting a link to the instance is possible when the data set is defined as a BPS data source. This means that the data source contains only the instances of another workflows.
