How to Use Field Dependency for Creating a Cascading Dropdown

Updated on : October 12, 2022

Field dependency creates a parent-child relationship (cascading effect) between two fields. For example, the parent field can be a Country while the child field can be a State. By using Field Dependency, you can set up a cascading dropdown. Example: Country, State, City, and Region.

Note: Field dependencies are not applied when an action is performed via email or automation.

Accessing the Field Dependency List

To access the Field Dependency list, follow the steps below:

  1.  Go to, Admin Panel > Field and Forms > Field Dependencies.
  2. In the field dependency table, you can view the following details:
    • Parent > Child field name
    • Last Modified Date
    • Status

The Dependency Field selection has three properties namely,

  • Module – Displays a list of Tickets, Contacts, and Contact Groups.
  • Parent Field – Displays a list of fields in the single-select dropdown list.
  • Child Field – Displays a list of fields in which either single-select or multi-select field can be selected.

Note:

  • A parent can have multiple child fields, but a child has only a single parent field.
  • Only after selecting the parent field, will the child field be enabled.

Mapping Field Dependency

To map a field dependency, follow the steps below:

  1. Select a Parent Field on the left panel first,
  2. Click on the corresponding child fields on the right panel.
  3. Map the value of the child field to the parent field.

    For example, in the image below, the country of the USA is mapped to the following states (Alaska, Louisiana, New Mexico, and New York). When the Country is set to the USA, only these four states will be displayed in the State field.
