Building flexible UI components is key when developing modern web apps. Recently, I implemented a dynamic “Main Route” section using React and react-hook-form, allowing users to add multiple route links and set a custom background color — all without leaving the form.
Using useFieldArray, users can add or remove route items (each with a name and href), and Controller makes managing input states seamless. Instead of relying on Tailwind’s static utility classes, I used an inline style={{ backgroundColor }} approach to handle dynamic color inputs — a more reliable method when working with unpredictable values.
Preview mode makes the UX intuitive, allowing users to toggle between editing and viewing their routes in real time. This kind of modular component not only improves developer productivity but also creates a better editing experience for end users.
It’s small touches like this that make form-driven UIs powerful and user-friendly.
