+## Environment
+
+
+
+
+
Product
+
+ Grid for Blazor,
+ TreeList for Blazor
+
+
+
+
+
+## Description
+
+Dropdown components do not open inside a Grid column `` when the Grid has [`Navigable="true"`](https://demos.telerik.com/blazor-ui/grid/keyboard-navigation).
+
+## Cause
+
+When the Grid keyboard navigation is enabled, the table cells automatically gain focus when a cell is clicked. If the cell contains a focusable element, this element may lose focus unexpectedly on click.
+
+## Solution
+
+Normally, editor components belong to [``]({%slug grid-templates-editor%})s, but this article assumes that editor templates are not an option. Thus, other possible options include:
+
+* If data operations like sorting and filtering are not necessary for the affected columns, place buttons or dropdown components like ComboBox or DropDownList inside a [Grid Command Column]({%slug components/grid/columns/command%}) instead. Grid command columns do not gain focus automatically when a nested focusable element is clicked.
+* If data operations for the affected columns are required, then use a container with `@onclick:stopPropagation` inside the `` template. This will prevent the Grid from knowing about the clicks, so the data cell will not gain focus automatically.
