v3.2.0

New Feature

• Support Block handle — line side handles provide hover, drag, and an action menu.
• SelectMenu now supports submenus.
• A toolbar_innerWidth and innerWidth option has been added.
• Support slashCommand plugin — a Notion/Tiptap-style command menu with a configurable trigger character (default /) and user-defined menu items.
• A placeholder_line option has been added — a Notion-style line placeholder shown at the cursor line when it is empty. When enabled together with placeholder, the line placeholder takes precedence on the focused empty line.

Enhancement

• Unified dropdown plugin menu creation onto a shared method. menu.initDropdownTarget(classObj, itemsOrNode, options?) now accepts an Array<DropdownItem> in addition to the existing Node argument, generating <button>/<li> markup internally (the existing Node signature stays compatible). A DropdownItem follows the { command, value?, title, innerHTML, className?, attrs? } schema, and the 10 built-in dropdown plugins (align, blockStyle, font, hr, layout, lineHeight, list, paragraphStyle, template, textStyle) were migrated to the new form.
• Coalesced the wysiwyg mousemove handler using requestAnimationFrame.
• Updated SelectMenu item hover/active colors to a blue tone.

Bugfix

• Fixed a bug where a pageBreak component could not be deleted with Delete/Backspace after being selected. #1670
• Fixed a bug where the distributed types (types/) for Hook.* (component/modal/controller/browser/colorPicker/hueSlider) were broken.
• Fixed a bug where SelectMenu did not flip left/right in left/right mode due to mixed coordinate systems.
• Fixed a bug where bullet markers overflowed outside the list by changing list-style-position to inside.
• Fixed a bug where the controller did not hide when its target scrolled out of view inside wysiwyg-inner, or stayed stuck at the editor edge.
• Fixed a bug where the placeholder position was misaligned in documentType.
• Fixed a bug where pressing Enter on an empty line (a line containing only <br>) created a new line above and left the cursor on the original line — the cursor now moves to the new line for empty paragraphs, list items, and headings.
• Fixed a bug where pressing Enter with an active selection (including full-line or multi-line selections) left the cursor on the upper line instead of the lower line.
• Fixed a bug where backspace/delete did not work on empty lines (e.g. created via Enter) in Firefox. #1671
• Fixed a bug where pasting into a table cell threw a JavaScript error and did nothing. #1668
• Fixed a bug where whitespace-only text such as   was removed during HTML cleanup. #1667
• Fixed a bug where HTML cleanup (e.g. value) converted whitespace between block elements (</p>\n<p>) into a dead line without <br> (<p></p>), or left a line break after an in-line <br> (<p><br>\n</p>) as whitespace.
• Fixed a bug where pressing Enter on an empty line or in an empty editor duplicated the paragraph (in an empty editor the wysiwyg container itself was cloned). #1657
• Fixed a bug where pressing Enter inside a PRE code block within a scroll-embedded editor scrolled to the whole PRE block instead of the line — scrolling now uses the actual cursor position after Enter.
