Z-Index & Overlay Mounting

All global overlays (bubble menus, BlockPicker, mention suggestions, AI popover, Ant Design Dropdown / Select / Popover / Modal / Tooltip, custom Toast / Notice, etc.) mount inside the overlay portal (.yaniv-editor__overlay-portal) on the EditorShell root—not on document.body. Overlays stay within the .yaniv-editor scope and inherit --ye-z-* CSS tokens correctly.

Exceptions (non-visual overlays):

• HTML5 drag preview nodes (setDragImage)
• Hidden <input type="file">

Host configuration

Both YanivEditor and YanivInlineEditor support zIndexBase (default 1000). The shell writes it to --ye-z-base on the editor root:

<YanivEditor :z-index-base="1500" />
<YanivInlineEditor v-model:content="html" :z-index-base="1500" />

This prop does not rebuild the session.

When to adjust

Scenario	Suggestion
Editor is main content	Keep default 1000
Host has fixed header / sidebar (z-index ~100–500)	Default is fine
Host global Modal / Drawer must cover editor overlays	Host layer > 1100 (see table), or lower editor zIndexBase
Editor nested inside a host Modal	Raise zIndexBase, or ensure host Modal is above the editor

To cover all editor overlays (including in-editor Modal), host UI must be above zIndexBase + 100 (default 1100).

Token ladder (variables.css)

Color tokens live on :root; z-index tokens are only on .yaniv-editor:

Token	Value (base=1000)	Use
--ye-z-content	1	In-document base
--ye-z-content-overlay	2	Table selection, etc.
--ye-z-content-control	10	Image column handles, etc.
--ye-z-editor-ui	20	Drag handle
--ye-z-editor-rail	30	Outline rail
--ye-z-chrome	40	Header / footer
--ye-z-chrome-tooltip	50	In-document tooltips (BaseTooltip, etc.)
--ye-z-overlay-backdrop	base	Block picker backdrop
--ye-z-bubble-menu	base + 10	Link / image / table bubble
--ye-z-floating-menu	base + 20	Selection floating menu
--ye-z-picker-menu	base + 30	BlockPicker, mention, AI popover
--ye-z-drag-menu	base + 40	Drag block menu
--ye-z-drag-submenu	base + 41	Drag submenu
--ye-z-dropdown	base + 50	Ant Design dropdown
--ye-z-tooltip	base + 60	Portal Ant Design Tooltip
--ye-z-toast	base + 80	Custom Toast / Notice
--ye-z-modal	base + 100	In-editor Modal

Order: modal > toast > tooltip > dropdown > drag-menu > picker-menu > floating-menu > bubble-menu > backdrop.

Toast / Notice

Do not use Ant Design static message / notification (global singleton, mounts to document.body, unsafe with multiple instances).

Unified APIs:

• Vue components: useOverlayFeedback() (src/composables/useOverlayFeedback.ts)
• Non-Vue / extensions: showEditorToast / showEditorNotice (src/core/overlayFeedback.ts)

All mount into the current editor's overlay portal.

Custom Shell checklist

If you build your own Shell instead of EditorShell:

1. Root has yaniv-editor class;
2. Root contains .yaniv-editor__overlay-portal (see src/styles/overlay-portal.css);
3. Call provideEditorRoot / provideOverlayPortal (src/core/editorContext.ts);
4. All teleport / BubbleMenu appendTo / Ant Design getPopupContainer / getContainer target the overlay portal;
5. Read portal tokens via getYeZIndex(token, root) (src/utils/zIndex.ts) with the editor root—no global fallback.

Library entry points:

• useOverlayMountTarget() — Ant Design getPopupContainer / Modal getContainer
• useOverlayBubbleMenu() — Tiptap 3 BubbleMenu (Floating UI) appendTo + options
• useOverlayFeedback() / showOverlayToast / showOverlayNotice — Toast / Notice
