Prerequisites

What is a ComboBox form field?

A ComboBox form field is a form field that allows the user to pick a value from a dropdown list or type free text.

Creating a ComboBox form field

1. If not already existing, create a data source in the Resource tab in the Admin Center with the desired schema, keep in mind you might want to have a label column that is different from the data you'd like to reference in bindings. A simple format would be to use the Name column for labeling and other columns for data.
2. Populate the rows of the data source with data you'd like to reference in templates
3. Go to the Form tab in Dynamics Designer
4. Click Add form field
5. Select Type ComboBox, fill in Name and Label fields, and set the desired options
6. In Datasource select the data source the form should be linked to 
7. In Label column select the column in the data source that should be displayed to the end-user
8. Click Save

Additional Options

• Required: Check this box if you'd like to mandate the user select an option, an asterisk will indicate to them that it's required.
• Default Value: Prepopulate an option for the user. The default value can be any value, e.g. a value present in the linked data source column, or your own custom text. You can also use a binding as default value, for example {{UserProfile.Location}} or {{HostSystem.Subject}}.
• Filter options: Filter the options of this ComboBox according to a data source.
• Spacing before: Add space above the form field.
• Spacing after: Add space below the form field.
• Helptext prefix: Add help text above the ComboBox, this can be useful for guiding the user on filling out the form field.
• Helptext postfix: Add help text below the ComboBox, this can be useful for guiding the user on filling out the form field.
• Share value: Allow the form field to be recognizable as shared by dynamic documents.
