Control Description

The Select List control provides either a checkbox- or multi-select drop-down menu-style control from which the Request participant selects one or more options.

Set options that display in this control in one of the following ways:

• Provide each option: For each option, enter a unique value that represents the option, and then enter the text that displays as the option. After your options are configured, sort the order in which they are to display in the control. Alternatively, provide options in the control in JSON format.

• Reference a data source in the JSON data model: Reference data from a ProcessMaker Data Connector that displays in this control as its options. Specify the data name, value, and content from the Data Connector. Optionally, use a PMQL expression to limit which data to use as options based on the PMQL expression's criteria. The order that data objects present in the data object determines the order these options display in the control; options cannot be manually reordered.

  ​

Checkbox Functional Description

When using the Select List control with checkboxes, the control functions similarly to multiple Checkbox controls whereby multiple options may be selected. Unlike using multiple Checkbox controls, the Select List control includes all selected options as an array in the order that options are selected. This array becomes part of the JSON data model as shown in the example below in Preview mode.

Drop-Down Menu Functional Description

When using the Select List control as the drop-down menu, multiple options may be selected one at a time. Selected options have the following attributes:

• Each selected option displays in the control.

• Each selected option displays in bold-style text in the drop-down menu. Furthermore, a red-colored highlight displays when mouse-hovering over a selected option, rather than the default green-colored highlight for deselected options.

Follow these guidelines to deselect an item from the Select List control when using the drop-down menu style:

• Click the imagefor the option to be removed.

• Select the option again from the drop-down menu.

The Select List control includes all selected options as an array in the order that options are selected. This array becomes part of the JSON data model as shown in the example below in Preview mode.

• ​Variable panel​

• ​Configuration panel​

• ​Data Source panel​

• ​Design panel​

• ​Advanced panel​

Variable Panel Settings

Click the control while in Design mode, and then click the Variable panel that is on the right-side of the Screen Builder canvas.

Below are settings for the Select List control in the Variable panel:

• ​Variable Name​

• ​Label​

• ​Validation Rules​

Variable Name

Edit the default Variable Name setting value for this control if necessary. The Variable Name setting value represents data in this control during Requests. Ensure that the Variable Name setting value is a unique name from other controls in this ProcessMaker Screen and contains at least one letter. This is a required setting.

Use the Variable Name setting value in the following ways:

• Reference this control by its Variable Name setting's value. The Data Preview panel in Preview mode corresponds the option(s) the Request participant selects in the Select List control with that Select List control's Variable Name value. The Variable Name setting contains the selected option(s) as an array. In the example below, SelectListControl is the Variable Name setting's value.

• Reference this control's value in a different Screen Builder control. To do so, use mustache syntax and reference this control's Variable Name value in the target control. Example: {{ SelectListControl }}.

• Reference this value in Visibility Rule setting expressions.

Label

Edit the default label that displays for this control if necessary. New Select List is the default value.

Validation Rules

Enter the validation rule(s) the Request participant must comply with to properly enter a valid value into this control. This setting has no default value. If there are no configured validation rules the following message displays: No validation rule(s). See Validation Rules for "Validation" Control Settings.

Configuration Panel Settings

Click the control while in Design mode, and then click the Configuration panel that is on the right-side of the Screen Builder canvas.

Below are settings for the Select List control in the Configuration panel:

• ​Placeholder Text​

• ​Helper Text​

Placeholder Text

Enter the placeholder text that displays in this control when no value has been provided. This setting has no default value.

Helper Text

Enter text that provides additional guidance on this control's use. This setting has no default value.

Data Source Panel Settings

Click the control while in Design mode, and then click the Data Source panel that is on the right-side of the Screen Builder canvas.

From the Data Source panel, select one of the following methods to specify options that display in the Select List control:

• ​Provide options: Enter a unique value that represents each option, and then enter the text that displays as the option. After your options are configured, sort the order in which they are to display in this control. Alternatively, provide options in this control in JSON format.

• ​Request data: Reference data from the in-progress Request as options in this control. This data object must be part of the Request's JSON data model. During the in-progress Request, the Select List control references a specified data array and object in the Request's JSON data model to display its values as options in that control. The order that data objects are in the Request's JSON data model determines the order these options display in the control; options cannot be manually reordered.

• ​ProcessMaker Data Connector: Reference the data from a ProcessMaker Data Connector's Endpoint as options in this control. Note that the ProcessMaker Data Connector package must be installed to your ProcessMaker instance for this option to be available. The Data Connector package is not available in the ProcessMaker open-source edition. Contact ProcessMaker Sales or ask your ProcessMaker sales representative how the Data Connector package can be installed in your ProcessMaker instance.

  These Endpoints a ProcessMaker Data Connector references may be Application Program Interface (API) endpoints, ProcessMaker Collection records, or other data source endpoints. During the in-progress Request, when the Select List control references data from the ProcessMaker Data Connector, the control maps the ProcessMaker Data Connector data to a specified JSON data array, variable or key name, or data object to become part of that Request's data. Data maps to the JSON data array in the same order it is retrieved from the ProcessMaker Data Connector. Optionally, use a PMQL expression to limit which data to use as options based on the PMQL expression's criteria. The order that data objects return from the ProcessMaker Data Connector determines the order these options display in the control; options cannot be manually reordered.

Provide Options

See the following procedures how to provide options for a Select List control.

Reference Request Data

Follow these steps to reference data from the in-progress Request as options in this control:

1. Access the Data Source panel for this control while in Design mode.

6. In the Value setting, enter the JSON key name from within the JSON data array selected from the Element Name setting to reference its objects as options that display in this control. Use JSON dot notation as necessary. value is the default value. Example: data.response.value

7. In the Content setting, enter the JSON object name that corresponds with the JSON key name selected from the Value setting's JSON key name to display its content as options in this control. Use JSON dot notation as necessary. content is the default value. Example: data.response.value.content

Reference a ProcessMaker Data Connector

Follow these steps to reference data from a ProcessMaker Data Connector as options in this control:

1. Access the Data Source panel for this control while in Design mode.

2. From the Data Source drop-down menu, select Data Connector.

3. Select the Allow multiple selections option to allow multiple selections from this control. Otherwise, only one option can be selected.

4. From the Render Options As drop-down menu, select one of the following options:

   • Dropdown/Multiselect: Select the Dropdown/Multiselect option to display the control as a drop-down menu.

   • Radio/Checkbox Group: Select the Radio/Checkbox Group option to display the control as a group of checkboxes.

5. From the Data Connector drop-down menu, select from which ProcessMaker Data Connector to reference as a data source. If a ProcessMaker Data Connector does not exist, this setting has no options.

6. From the Endpoint drop-down menu, select which Endpoint to reference from the selected ProcessMaker Data Connector. These Endpoints are configured from the ProcessMaker Data Connector itself. Depending on the ProcessMaker Data Connector selected from the Data Connector Name drop-down menu, these Endpoints may reference API endpoints, ProcessMaker Collection records, or other data source endpoints.

7. In the Element Name setting, enter the name of the JSON data array within the selected ProcessMaker Data Connector from which to reference its objects as options that display in this control. This JSON data array and its content becomes part of that Request's data. Use JSON dot notation as necessary. response is the default value.

8. In the Value setting, enter the JSON key name from within the JSON data array selected from the Element Name setting to reference its objects as options that display in this control. Use JSON dot notation as necessary. value is the default value.

9. In the Content setting, enter the JSON object name that corresponds with the JSON key name selected from the Value setting's JSON key name to display its content as options in this control. Use JSON dot notation as necessary. content is the default value.

10. In the PMQL setting, optionally enter a PMQL expression to filter which data in the JSON data array to display as options in this control based on which objects in that array meet the PMQL expression's criteria.

Consider the following example of doctors who work in a clinic.

doctors = [
    {id: 1, name: 'Adam Ardin', gender: 'male'},
    {id: 2, name: 'Amanda Creek', gender: 'female'},
    {id: 3, name: 'Lucy Morales', gender: 'female'},
    {id: 4, name: 'Mindy Smith', gender: 'female'},
    {id: 5, name: 'Toby Tomlinson', gender: 'male'}
]

Use the following settings to reference this data array as options for this control:

• Element Name: doctors

• Value: id

• Content: name

Suppose that a new patient at the clinic indicates that she wants to see a female doctor. To filter doctors from this JSON data array who are female in the clinic so that only those objects display as options in a Select List control, use the following PMQL expression in the PMQL setting of that control:

gender = "female"

Design Panel Settings

Click the control while in Design mode, and then click the Design panel that is on the right-side of the Screen Builder canvas.
