Input Upload

A file upload input rendered as a labelled dropzone surface with a centered icon, title, helper description, and a styled trigger affordance. The whole surface is clickable to open the native file picker and accepts drag-and-drop. Drag state and selected files are owned by the shared core package, so Astro and Svelte adapters consume the same headless logic.

Feedback

Apply semantic feedback colors to indicate validation state or context (for example, a red dropzone after rejecting an oversized file).

Size

Four sizes scale the dropzone’s min-height, padding, icon, and typography together.

Slots

Override any slot — icon, title, description, or trigger — to customize the dropzone content. Pass strings via the matching props (title, description, triggerLabel) for simple text overrides, or use named slots / snippets for rich content.

Custom Styling

The passThrough prop provides per-slot escape hatches: style accepts a Panda CSS SystemStyleObject and props forwards arbitrary HTML attributes onto the slot element.

Upload Button

For compact entry points where a full dropzone is overkill, use the sibling <UploadButton> component. It renders a real Pindoba <Button> that opens the file picker on click and still accepts drag-and-drop on its surface. Forward emphasis and feedback to pick the button look — they’re passed straight through to the underlying button.

Validation

Built-in validation rejects files that exceed maxSize, surpass maxFiles, fail imageDimensions checks, or are flagged by a custom validate function. Rejected files are reported via onReject (Svelte) or a pindoba:reject CustomEvent (Astro). Combine with feedback="danger" to indicate the error state.

In Astro, custom function-based validators are registered on window.pindobaValidators and referenced by name through the validatorName prop, since functions can’t be passed through frontmatter to inline scripts.
