+

+
+### Example
+
+~~~jsx {6}
+const spreadsheet = new dhx.Spreadsheet("spreadsheet_container", {
+    // config parameters
+});
+spreadsheet.parse(data);
+
+spreadsheet.selection.disable();
+~~~
+
+### Details
+
+The method:
+
+- ends the editing of a cell and saves the entered value
+- removes the selected and the active cells on every sheet
+- ignores the selection by the mouse, the keyboard and the API until the [`enable()`](api/selection_enable_method.md) method is called
+
+While the selection is turned off, the [`getSelectedCell()`](api/selection_getselectedcell_method.md) and [`getFocusedCell()`](api/selection_getfocusedcell_method.md) methods return `undefined`. The other effects are the same as for the [`selection: false`](api/spreadsheet_selection_config.md#details) configuration option.
+
+If the selection is already turned off, the method does nothing.
+
+**Change log:** Added in v6.0.4
