Forms & Inputs

Build a floating-label text input. 56px tall, rounded-xl, background rgba(255,255,255,0.03), 1px border rgba(255,255,255,0.08). The label sits at the vertical center at rest in ink-400; on focus or when the input has a value, it animates to the top-left, shrinks to 11px, and lifts above the field's visual baseline. Smooth 180ms cubic-bezier transitions. On focus the border brightens to rgba(255,255,255,0.24). Include error state with a red 1px border and an inline message below the input.

Build a multi-step form. Top: a thin progress bar (4 segments, current segment fills smoothly). Below the bar: the current step number and label ("Step 2 of 4 · Your team"). Center: the step content, vertically centered, max-width 480px. Bottom-fixed bar: "Back" ghost button on the left, "Continue" primary button on the right. Animate between steps with a horizontal slide + fade. Each step content is its own form-section component with title, optional description, and inputs.

Build an inline-validated input. Standard rounded-lg input with a trailing icon slot that renders a small check (success), x (error), or spinner (validating). Validate on blur for sync rules; async validation (e.g. email availability) debounces 200ms after typing pauses. On error, the border turns danger color and a 12px message renders beneath the input with role='alert'. On success, the border stays neutral but the trailing icon shows the check.

Build a combobox using Radix Popover + cmdk (or a comparable headless primitive). Trigger renders the selected option (or 'Select…') with a chevron. Open shows a popover anchored to the trigger with a search input at the top (autofocus on open), and a virtualized list of options below. Each option has a leading icon or avatar, label, and optional muted subtitle. Arrow keys cycle, Enter selects, Esc closes. Pluggable async loader: while pending show a spinner row, on empty show 'No matches'.

Build a tag multi-select. The field renders as a flex-wrap row of removable chips followed by a caret input. Each chip has a label + 'x' button. Backspace on empty input removes the last chip. Focusing the input opens a popover with filterable options; pressing Enter on a typed value not in the list shows a 'Create "{value}" +' row. Selected options remain visible at the top of the dropdown with a check. ArrowUp/Down cycles, Esc closes.

Build a date range picker. Trigger button shows the current range ('May 1 – May 27') with a calendar icon. Popover opens with a left preset column (Today, Yesterday, Last 7 days, Last 30 days, Month to date, Custom) and a right calendar showing 2 months side-by-side. Clicking start sets the start, hovering paints the range, clicking end commits. Both months keyboard-navigable; Shift+Arrow extends the range. Apply button at the bottom closes the popover and fires onChange.

Build a file drop zone. Bordered (2px dashed line) rounded-2xl container, min-height 180px, centered icon + 'Drop files here or click to browse' copy. On dragenter, the border solidifies and turns accent color. Files dropped or selected via the hidden <input type=file> appear below the zone as a list. Each row shows file name, size, a progress bar that fills as the file uploads, and an 'x' cancel. Validate type (accepted MIME list) and size; show inline error per offending file.

Build an address autocomplete field. A search-style input with a leading map-pin icon and 'Start typing your address' placeholder. As the user types, debounce 180ms and call the Google Places autocomplete endpoint, rendering a popover list of predictions below the input. Each prediction: street primary line in 14px, locality in 13px muted. On select, fetch the place details and populate the line1, line2, city, state, postal, and country inputs that live just beneath the autocomplete in the form. Add a small 'Enter manually →' link to skip autocomplete.

Build a phone number input using libphonenumber-js. Left side: a small button with the selected country's flag emoji + dial code; click opens a searchable country list popover. Right side: the local-number input that auto-formats as the user types based on the selected country. The component emits the E.164 representation as its onChange value. On mount, attempt to default the country via the browser's locale or a /api/geo endpoint. Show inline validation on blur (invalid number → border + message).

Build a signature pad. A bordered rounded-md canvas (480×160). Show a faint 'Sign here' watermark centered when empty. Draw with mouse + touch + pen pressure (pointer events), use Catmull-Rom smoothing for natural strokes. Top-right of the canvas: a small 'Clear' button (icon + label). Above the canvas, a tab row with Draw / Type / Upload. Type renders the typed name in a script font; Upload accepts a PNG. Component emits the current signature as a base64 data URL.
