==Overview==
The article describes how to configure conditional lists of values in custom field. These lists, also known as dependent dropdown lists, change their available options based on the selection made in another, related field (the Parent Field). This functionality is applicable to custom fields:
* [[Custom Field Type: Select Many – Check Boxes|Select Many – Check Boxes]]
* [[Custom Field Type: Select One - Dropdown List]]
The article explains the configuration process using the '''ssOption''' syntax and provides examples of how these conditional lists work in practice.
==Configuration==
The list of values selectable in a custom field can be made conditional upon the value selected in another custom field. This functionality can be configured on the following [[:Category:Custom Field Types|custom field types]]:
{||-||[[Image:Canada-Ontario-Cities.jpg|link=]]||or||[[Image:US-Texas.jpg|link=]]|}
To configure this functionality, for each dependent field:
* Define the field that will condition the dependent values as the "Parent Field".* In the settings page of the "Child Field", there's a drop down field called "Parent Field" - this must be populated with the "Parent Field" being referenced.* Surround the dependent values with the '''ssOption''' syntax: <font size="3"pre><ssOption: ''Parent Value 1''>;''Dependent Value 1'';''Dependent Value 2''</ssOption></fontpre>
In the configuration shown below:
* In the ''Province'' field
**''--Select One--'' will always be shown,**''Ontario'' and ''British Columbia'' will only be shown if ''Canada'' is selected in the ''Country'' field, and**''Texas'' will only be shown if ''United States'' is selected in the ''Country'' field. <pre>--Select One--<ssOption:Canada>;Ontario;British Columbia</ssOption><sOption:United States>;Texas</ssOption></pre> *In the ''City'' field**''-- N/A --'' will always be shown,**''Toronto'' and ''Ottawa'' will only be shown if ''Ontario'' is selected in the ''Province'' field, and**''Vancouver'' will only be shown if ''British Columbia'' is selected in the ''Province '' field. <pre>--N/A--<ssOption:Ontario>;Toronto;Ottawa</ssOption><ssOption:British Columbia>;Vancouver</ssOption></pre>

==Note==* Any number of lists of values can be made dependent on other lists of values.* This feature will not work in conjunction with [[Custom Field Type: Dynamic Data – Dynamic Control Field|Dynamic Control fields]].* This feature will not work with [[Standard Field|Standard Fields]] e.g. Application Type. Even if standard field is available to select as a '''Parent Field'''.
