Vastuskastid

Vastuskastid are user interface elements used to collect user responses in digital forms and assessments. They appear in online surveys, contact forms, quizzes, and feedback tools, and vary in complexity from simple text inputs to structured answer options.

The most common types include single-line text fields, multi-line text areas, radio buttons for a single choice, checkboxes for multiple choices, drop-down menus, date and time pickers, numeric inputs, sliders, and file upload controls. Rating scales and autocomplete suggestions are also common.

Good design emphasizes clear labels, concise instructions, and accessible validation. Placeholders should not replace labels. Required fields should be indicated. Validation should be immediate when possible and provide actionable error messages. Forms should be responsive and work on assistive technologies.

Accessibility considerations include proper labeling, keyboard operability, screen reader compatibility, sufficient color contrast, and grouping related fields with fieldsets and legends. Data input should support input masking where appropriate (phones, dates) and provide helpful hints.

Data handling involves collecting responses securely, respecting privacy, and complying with relevant regulations. Minimize data collection, store only necessary information, and implement access controls. Inform users about how their data will be used and retained.

In practice, vastuskastid are found in student assessments, customer feedback portals, and registration forms. They may be static or dynamic, adapting to previous answers, and can include logic to reveal or skip fields.

The term derives from Estonian vastus (answer) and kast (box). It is used in Estonian-language interfaces and documentation to refer to answer fields in forms and quizzes.
