# Menu
Menu that provides navigation for your website.
::: tip
If you want to override the default height of el-menu, you can use the following CSS:
```css
.el-menu--horizontal {
--el-menu-horizontal-height: 100px;
}
```
:::
## Top bar
Top bar Menu can be used in a variety of scenarios.
:::demo By default Menu is vertical, but you can change it to horizontal by setting the mode prop to 'horizontal'. In addition, you can use the sub-menu component to create a second level menu. Menu provides `background-color`, `text-color` and `active-text-color` to customize the colors.
menu/basic
:::
## Left And Right
:::demo You can make the menu items to the left or right.
menu/left-and-right
:::
## Side bar
Vertical Menu with sub-menus.
:::demo You can use the el-menu-item-group component to create a menu group, and the name of the group is determined by the title prop or a named slot.
menu/vertical
:::
## Collapse
Vertical Menu could be collapsed.
:::demo
menu/collapse
:::
## Popper Offset ^(2.4.4)
Menu with popperOffset will override Submenu's `popper-offset`.
:::demo
menu/popper-offset
:::
