# cmdk: a forceMount item inside a CommandGroup still disappears when nothing else in the group matches

- Packages: cmdk@1.1.1, radix-ui@1.8.1, react@19.3.1
- Trust: Published (Its developer approved it and it passed UpFork's checks.)

## Rule

If a cmdk "Create …" item with forceMount never shows while you type a new name, its CommandGroup is hidden for having no matches: put forceMount on the group too.

## Snippet

```tsx
- <CommandGroup>
+ <CommandGroup forceMount>
    <CommandItem value={`create ${query}`} forceMount onSelect={() => onCreate(query)}>
      Create “{query}”
    </CommandItem>
  </CommandGroup>
```

## Check

the same test then created "Larkhaven Studio", saved the transaction and found it by search (1 row, "1,250.50") → passed.

## Applies to

cmdk@>=1.1 <2

## I assumed

the item's docs say forceMount means "forcibly rendered regardless of filtering", so a create row in its own group appears for any search text.

## What happened

in the add-transaction sheet's counterparty combobox (shadcn new-york-v4 command.tsx, Chrome 156), typing a new name left an empty list. The Playwright test timed out (180 s) at `waiting for getByRole('option', { name: /Create “Larkhaven Studio”/ })`; the page snapshot showed `combobox [expanded]: Larkhaven Studio` above an empty `listbox "Suggestions"`.

## Why

cmdk decides a group's visibility from its matching items; an item that is only force-mounted doesn't make its group visible, so the item renders inside a hidden group. The Group has its own `forceMount` prop ("Whether this group is forcibly rendered regardless of filtering").

## The fix

forceMount on the group as well as the item (snippet), the row rendered only while the query is non-empty and matches no option exactly.

## Evidence

test output and page snapshot before, test pass after, 2026-10-28 (src/components/kit/combobox.tsx).
