What changed

The repeatable field-item dialog (FieldRenderer in modules/System/assets/vue-components/fields/renderer.js) is the generic "add/edit item" modal used by every field type with multiple: true — including the select field's Options settings, which is what issue #127 reports on.

Previously pressing Enter inside that dialog did nothing; you had to click "Update item"/"Add item" with the mouse. This PR:

  • Adds a keyup.enter handler on the dialog content that calls the same saveFieldItem() method the button uses, so Enter now submits the item.
  • Guards the handler so it does not fire when the focused element is a <textarea> or a contenteditable element, so multi-line inputs still insert a newline on Enter instead of submitting.
  • Also guards against double-firing when a <button> or <a> (e.g. the Cancel link, or the Save button itself) already has focus and receives the native Enter-triggered click — without this guard, tabbing to Cancel and pressing Enter would close-then-resave, and tabbing to the Save button would double-submit.
  • Autofocuses the dialog's first input/textarea/select when it opens (via a fieldItem watcher + nextTick), per the second half of the issue ("input field should be autofocused").

Why here and not just the select field

The dialog markup and saveFieldItem/addFieldItem/editFieldItem methods are shared by all field.multiple field types (select options, tags, object lists, etc.), not just select. Fixing it at this shared level resolves the reported select-options case and keeps behavior consistent everywhere the same dialog is reused, rather than patching one field type.

Test plan

  • php is not available in my environment, so I could not boot Cockpit's admin UI to manually click through the dialog in a browser.
  • Verified: node --check on the modified file passes (valid syntax).
  • Verified: ran the project's own npm run build-bundle (rollup) against the changed source — it bundles cleanly with no new errors/warnings beyond a pre-existing, unrelated this-at-top-level notice in a vendored dompurify.js file. I reverted the generated app.bundle.js/app.bundle.css output itself since it isn't meant to be part of this source diff.
  • Read through all other consumers of <fields-renderer>/<field-renderer> (field-nav.js, field-set.js, manager.js, content-preview.js, form.js, batch-edit.js, asset.js) to confirm none of them depend on the previous (no-op) Enter-key behavior inside this dialog, and confirmed via manager.js that the select field's "Options" settings panel renders through this exact same field.multiple → dialog path.
  • Gap: no existing JS test harness covers this component (repo has no JS test runner configured), and I did not get real-browser confirmation that focus lands correctly across every field type (e.g. custom third-party field types with non-standard focusable elements). Would appreciate a maintainer or CI browser check on this before merge.

Closes #127

Summary by CodeRabbit

  • New Features

    • Editable field dialogs now focus the first enabled, visible input, including nested controls that appear as content loads.
    • Pressing Enter saves field items from supported controls.
  • Bug Fixes

    • Focus retries while nested controls finish rendering, improving reliability when dialogs open.
    • Enter no longer triggers unintended saves from buttons, links, textareas, editable content areas, or while composing text.
    • Dialogs prevent default browser behavior when Enter saves a field item.

📝 Walkthrough

Walkthrough

FieldRenderer defers autofocus, selects an eligible input, and retries while nested fields render. Enter handling now runs on keydown and saves eligible field items while excluding IME, prevented, and non-input events.

Changes

Field item dialog interaction

Layer / File(s) Summary
Dialog focus and Enter-key handling
modules/System/assets/vue-components/fields/renderer.js
The fieldItem watcher defers focus through $nextTick. Focus selection excludes disabled, non-editable, hidden, and undersized controls, then retries for up to 60 animation frames. Dialog Enter keydown events invoke onFieldItemKeydown, which prevents the default action and saves eligible field items while excluding IME composition, buttons, links, textareas, contenteditable elements, and already-prevented events.

Add browser coverage for the dialog interaction contract.

Verify these cases in a browser:

  • The select Options dialog focuses its first usable control after opening.
  • Enter saves from a single-line input and select.
  • Enter inserts a newline in a textarea and contenteditable control.
  • Enter on the Update and Cancel controls does not invoke saveFieldItem() twice.
  • The behavior works for at least one other multiple: true field type.

This request follows the supplied test-plan note that browser-based testing was not performed.

Pushed a follow-up commit (1fa69d3) addressing all findings from the independent review and CodeRabbit:

  1. Autofocus was inert — the $nextTick fired before the nested field-renderer's async FieldTypes.get() resolved, so its DOM didn't exist yet. Replaced with a bounded requestAnimationFrame poll (~1s) that retries until a genuinely focusable control appears.

  2. Enter guard was unsafe — switched from keyup to keydown and added an evt.defaultPrevented check. Since app-tags' own keydown listener sits on the input itself (deeper in the DOM) and runs during the bubble phase before our listener on the ancestor kiss-content, its preventDefault() on Enter is already visible to us — this naturally excludes tags fields (and any other widget with its own Enter handling) without a hardcoded allowlist. Also added an isComposing/keyCode === 229 guard for IME composition, and moving to keydown structurally removes the keydown/keyup focus-race on the "Add item" button (there's only one keydown event per physical press, dispatched before the dialog/new focus target exist).

  3. CI regression — added braces to the two single-line conditionals (if (!dialog) return;, if (input) input.focus();) that were the only brace-less code introduced by this PR.

  4. Non-focusable selector match (CodeRabbit) — the focus-target picker now skips disabled elements, contenteditable="false", and offscreen/near-zero-size controls (covers CodeMirror's hidden measuring textarea in field-code/field-object).

Verified with node --check and a full npm run build-bundle (bundle output reverted from the diff afterward, source-only change). No JS test runner in this repo, so this is still pending a manual browser pass, but the logic path for each finding above is traced against the actual widget code (app-tags.js, field-boolean.js, field-code.js).

Good catch — restored in 95f3775. evt.isComposing is unset on keyup in some engines around IME composition, so the keyCode === 229 legacy fallback (dropped in eb2b084 during cleanup) was worth keeping as defense-in-depth. Both checks now guard the Enter handler.

…kpit-HQ#127)

- keyup.enter on the field-item dialog now triggers saveFieldItem()
  (same action as clicking Update item/Add item), instead of doing nothing
- guarded so textarea/contenteditable inputs still get a normal newline,
  and so focused Cancel/Save buttons don't double-fire the action
- the dialog's first input/textarea/select is now autofocused when it opens

Fixes the select field options editor per the issue, but the fix lives in
the shared repeatable-field-item dialog (FieldRenderer), so it applies to
every field type that uses field.multiple (tags, object lists, etc.), not
just select options.
…Q#127)

- Wait for the nested field-renderer to actually render before focusing,
  instead of a single $nextTick that fires before FieldTypes resolves
- Switch Enter handling from keyup to keydown and bail on
  evt.defaultPrevented, so widgets like app-tags that already handle
  Enter on keydown are not double-triggered, and the keydown/keyup
  focus race around the Add item button no longer applies
- Ignore Enter that commits an IME composition (isComposing / keyCode 229)
- Skip disabled, contenteditable=false, and offscreen/zero-size controls
  (e.g. CodeMirror's hidden measuring textarea) when picking the
  autofocus target
- Add braces to the two single-line conditionals that broke the
  DeepSource JavaScript check
The fieldItem watcher called focusFieldItem() synchronously, but the
teleported kiss-dialog it targets is gated by v-if and mounts on the
DOM-patch flush, which runs after Vue's default 'pre' watcher flush.
focusFieldItem() bailed on the missing dialog without scheduling the
bounded requestAnimationFrame retry, so autofocus never ran. Wrapping
the call in $nextTick defers it past the DOM patch so the dialog (and
its retry loop) is reachable.
