Imagine your respondents encountering endless, irrelevant choices in your form. Sounds frustrating, right? Zoho Forms Choice-based Field Rules offers a solution for this. You can create a dynamic picklist that filters options based on the selection made in another field.

Consider these scenarios:

Product Inquiry Form: When a user selects a "Product Category" (e.g., Electronics, Clothing, Books), the "Product Name" dropdown updates to show items only within that category.

Help Desk Ticket Form: When a user selects a "Problem Type" (e.g., Hardware, Software, Network), the "Specific Issue" dropdown shows problem related to that type.

Webinar Registration Form: When a user selects a "Departmant" (e.g., Marketing, Sales, Development, Human Resource), the "Webinar Topic" dropdown shows topics related to that specific department.

Field whose selection will update the options in another field. Let's take the Webinar Registration Form example, here the Parent Field is Department.

1) Create a new rule in Choice-based Field Rule under Rules tab.

2) Select the Primary and Secondary field.

3) For each primary field choice map the corresponding dependent field choice that needs to be displayed in the live form.

4) Click Save.

Thoroughly test your form with different selections in the primary field to ensure the dependent field updates and shows relevant choices.
