# Build Conditional Website Forms in Monticello

Show additional questions only when earlier answers make them relevant, and keep validation, error handling, and maintenance understandable across every branch.

Conditional logic is useful when one customer answer genuinely changes which information the business needs next.

It is less useful when a simple form is turned into a questionnaire simply because branching is available.

## Start with the workflow decision

Each branch should have a reason.

For example, selecting one service may reveal a question that only applies to that service.

If the answer does not change routing, preparation, price calculation, eligibility, or another real decision, the extra branch may not be necessary.

## Keep hidden fields truly inactive

A field that disappears from view should not continue blocking submission as an invisible required field.

Validation needs to match the active branch on both the client and server.

Current browser guidance is clear that client-side validation improves usability but cannot be trusted as the only validation layer.

## Test every path

A conditional form should be tested branch by branch for:

- completion;
- backtracking;
- changed answers;
- required fields;
- error messages;
- final submitted values.

The least common branch often reveals logic mistakes that the default path hides.

## Keep the logic readable

Staff or future developers should be able to understand why a question appears.

Document the branch conditions rather than scattering unexplained show-and-hide rules throughout the form code.

## Do not hide important terms

Conditional logic should simplify irrelevant questions, not conceal material costs, requirements, or conditions until late in the process.
