Description
Skaym Dependent Dropdowns for Forminator lets Forminator Single Select fields control which options appear in other Single Select fields.
Example:
- Department: Cardiology -> Doctor A, Doctor B
- Department: Dentistry -> Doctor C, Doctor D
You can create multiple independent Parent -> Child dependencies in the same Forminator form. Each Select field can participate in one dependency, so the free plugin is designed for independent pairs rather than multi-level chains.
Need a chain such as Department -> Doctor -> Room, or one field participating in several relationships? Get the separate Pro plugin, which adds chained dependency graphs.
Key features:
- Multiple independent Parent -> Child Select relationships per Forminator Custom Form.
- Uses existing Forminator Single Select fields and option values.
- Resets the child field when the parent selection changes.
- Validates the configured relationship on the server during submission.
- Keeps configuration separate for each Forminator form.
- Keeps each independent dependency pair on distinct Select fields.
- Detects removed or changed fields/options and asks for review.
- Does not send form or configuration data to an external service.
This is an independent third-party extension for Forminator and is not affiliated with or endorsed by WPMU DEV.

FAQ
-
Which Forminator fields are supported?
-
Forminator Custom Form Select fields using Single selection. Multi-select fields are not supported.
-
Can I create multiple dependencies?
-
Yes. You can create multiple independent dependency pairs in a form. Each pair must use distinct Select fields. Multi-level chains and relationships that reuse a field are provided by the separate Pro plugin linked in the Description.
-
Why should the child field have a placeholder?
-
A placeholder gives the child field a clear value to reset to when the parent selection changes.
-
Can I use Forminator’s Other option?
-
No. Other allows arbitrary custom values that cannot be mapped reliably. Disable Other on every Select field used in the dependency.
-
What happens if I remove a mapped Forminator field or option?
-
The plugin stops using invalid references at runtime and marks the saved configuration for review. Return to Forminator -> Dependent Dropdowns, review the mapping, and save again.
-
Does the plugin only hide options in the browser?
-
No. It also validates the configured parent-child relationship on the server during Forminator submission.
-
Does it send data to an external service?
-
No. The plugin does not send its configuration or form submission data to an external service.
