12.1.5 - 2026-10-19

Improvements

• Validators get a PopupPosition parameter that shows a popup validator above, below, to the left or to the right of its field. Bottom stays the default, so existing validators look the same. The popup stays next to its field when the layout changes, and a validator positioned while its field is hidden, for example on submit with the field in an inactive tab or a collapsed panel, is placed once the field is shown instead of off-screen (#640).

Fixes

• HtmlEditor table commands keep working after a row or column is deleted. Deleting the active row or column left the caret outside any cell, so the next table command failed. The caret now moves to a remaining cell, which is highlighted. Context menu commands restore the clicked cell's selection and close the menu even when the command fails, and right-clicking a cell no longer scrolls the editor. An inserted row gets the table's full column count when cells are merged with colspan, and the internal rz-html-editor-cell-selected class is no longer saved in Value. Thanks to @Radium001!
• DataGrid renders a column bound to a nullable enum with FilterMode.Simple in trimmed Blazor WebAssembly apps instead of throwing ArgumentException (NotAMemberOfType). The "No value" entry of the filter dropdown was an anonymous type whose properties the trimmer removed. It is now a DropDownItem<object>, like the enum entries.
