Docx Editor

Minor Changes

• 362a65f: Make block-level content controls (w:sdt) editable. Block structured document tags wrapping paragraphs or tables now convert to a dedicated ProseMirror node, so their content stays editable and the control survives the full edit cycle (previously it round-tripped on save but was flattened in the editor). The control boundary is drawn around its content in the paged view, and the region remains addressable by its tag/alias.
• d791e05: Add a content-control (SDT) addressing API to the headless surface. findContentControls/findContentControl discover block-level content controls by tag, alias, id, or type and read their text plus modeled state (showingPlaceholder, checked, dateFormat, listItems, dataBinding); setContentControlContent fills a control by tag (string or block content) and removeContentControl deletes or unwraps one. Edits preserve the control's identity and raw properties so the document still round-trips, clear the w:showingPlcHdr placeholder flag when writing real content, and refuse locked controls, typed controls (dropdown/date/…), and repeating-section unwraps unless forced. Makes content controls usable as stable anchors for templates and document automation.
• d791e05: Add content-control (SDT) methods to the editor ref. getContentControls lists block controls in the live document (filtered by tag/alias/id/type) with their text and position; scrollToContentControl brings one into view; setContentControlContent fills a control by tag (as a normal undoable edit); removeContentControl deletes or unwraps one. Locked controls are refused unless forced. Paired across the React and Vue adapters.
• a60ed77: Add typed value setters for content controls. setContentControlValue (headless) and the setContentControlValue editor-ref method (React + Vue) set a dropdown selection, toggle a checkbox, or set a date by tag, updating both the visible content and the structured w:sdtPr state (dropdown w:lastValue, w14:checked, w:date's w:fullDate). Validates the value against the control type and list items.
• a60ed77: Support repeating sections (w15:repeatingSection) with add/remove, matching Word. addRepeatingSectionItem/removeRepeatingSectionItem (headless) clone an item with fresh unique ids or drop one (keeping at least one); the editor renders ＋/✕ affordances on each repeating item in React and Vue. Items round-trip losslessly.

Patch Changes

• e30c763: Preserve block-level content controls (w:sdt) on save. Block-level structured document tags wrapping paragraphs or tables were silently dropped when a document was loaded and re-saved; they now round-trip losslessly, including their tag, alias, lock, and other properties. Fixes #622
• bc67374: Fix paragraph styles on empty paragraphs and the style that follows a heading on Enter. Applying a heading style to an empty paragraph and then typing now produces styled text instead of plain body text, and the style picker shows the right state. Pressing Enter at the end of a heading now starts the next paragraph in the style's follow-on style (body text) instead of another heading.
