About this block

Card Composer Column is the Acme platform board frozen in the add card state: the first column, To Do, has an open inline composer with a labelled title field, picker chips for label, owner, due date, and estimate, and Add card and Cancel actions. The sibling columns keep their closed add affordance at the foot of the stack.

Columns and cards are a typed array, and the composing state is keyed to a single column id, so only one composer is open at a time. The chips are static stand ins for real pickers, and the note under the actions tells a person where the new card will land once it is saved.

When to use

Reach for this block when people add cards often and you want capture to stay in place, typically a working board where breaking out to a modal would lose the flow. Wire the field and chips to your create endpoint and drop the new card at the bottom of the column.

A natural flow around it on an Application Pro page:

Before

• Board header toolbar
• Kanban board

After

• Card detail blueprint
• Tasks and todos

What you can display

One strong use is the product delivery board. Other inline composers:

• Task list. Add a to do with a due date and owner without leaving the list you are in.
• CRM pipeline. Log a new deal straight into the stage column where it belongs.
• Content board. Capture an idea card with a tag and a target date the moment it comes up.

Tip: keep the composer where the card will appear; an inline add reads as continuous with the column, while a modal breaks the person out of it.
