Composer tray with removable attachments

For AI Agents

Hand your agent this brief or the ReUI MCP, not a screenshot. Free to install.

Best for: A chat textarea topped by xs chips that scroll sideways, a paperclip that adds files and a live attached count

When to use

Files carried by a chat turn, as chips in a composer tray or cards in an assistant reply
Upload queues and pickers where each file reads as idle, uploading, processing, failed or done
Rows of image thumbnails or file chips that scroll sideways on one line instead of wrapping

When not to use

Picked files from the system dialog, checked against count, size and type limits: use the Attachment File Picker example
A drop zone that takes files dragged in from the desktop: use the File Upload component
A colored format badge that labels a document by its extension, such as PDF: use the File Type component
An upload list where each row needs a bar filling toward 100 percent: use the Progress component

Agent notes

The paperclip appends the next entry of FILES rather than opening a file dialog; wire a real picker as in c-attachment-6
The form onSubmit only calls preventDefault, so Send posts nothing until you add your handler
Attachment uploads nothing and only styles the state you pass, so set state from your own transfer code
The radix Button behind AttachmentAction sets no type, so pass type button inside a form or it submits
