+By default, tabs appear in the left sidebar. To display them horizontally in docs.yml, set `tabs-placement` to `header` in your layout configuration.
+
+`tabs-placement` supports two values:
+- `sidebar` *(default)* — Tabs are displayed vertically in the left sidebar.
+- `header` — Tabs are displayed horizontally in the top navigation bar.

+Example:
+
+<CodeBlock title="docs.yml">
+```yaml
+layout:
+  tabs-placement: header
+```
