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:

.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.
