This page assumes you've already read the Components Basics. Read that first if you are new to components. Slot Content and Outlet ​ We have learned that components can accept props, which can be JavaScript values of any type. But how about template content? In some cases, we may want to pass a template fragment to a child component, and let the child component render the fragment within its own template. For example, we may have a component that supports usage like this: template < FancyButton > Click me! The template of looks like this: template < button class = "fancy-btn" > < slot > The element is a slot outlet that indicates where the parent-provided slot content should be rendered. And the final rendered DOM: html < button class = "fancy-btn" >Click me! With slots, the is responsible for rendering the outer (and its fancy styling), while the inner content is provided by the parent component. Another way to understand slots is by comparing them to JavaScript functions: js // parent component passing slot content FancyButton ( 'Click me!' ) // FancyButton renders slot content in its own template function FancyButton ( slotContent ) { return `R${ slotContent } ` } Slot content is not just limited to text. It can be any valid template content. For example, we can pass in multiple elements, or even other components: template < FancyButton > < span style = "color:red" >Click me! < AwesomeIcon name = "plus" /> By using slots, our is more flexible and reusable. We can now use it in different places with different inner content, but all with the same fancy styling. Vue components' slot mechanism is inspired by the native Web Component element, but with additional capabilities that we will see later. Render Scope ​ Slot content has access to the data scope of the parent component, because it is defined in the parent. For example: template < span >{{ message }} < FancyButton >{{ message }} Here both {{ message }} interpolations will render the same content. Slot content does not have access to the child component's data. Expressions in Vue templates can only access the scope it is defined in, consistent with JavaScript's lexical scoping. In other words: Expressions in the parent template only have access to the parent scope; expressions in the child template only have access to the child scope. Fallback Content ​ There are cases when it's useful to specify fallback (i.e. default) content for a slot, to be rendered only when no content is provided. For example, in a component: template < button type = "submit" > < slot > We might want the text "Submit" to be rendered inside the if the parent didn't provide any slot content. To make "Submit" the fallback content, we can place it in between the tags: template < button type = "submit" > < slot > Submit Now when we use in a parent component, providing no content for the slot: template < SubmitButton /> This will render the fallback content, "Submit": html < button type = "submit" >Submit But if we provide content: template < SubmitButton >Save Then the provided content will be rendered instead: html < button type = "submit" >Save Named Slots ​ There are times when it's useful to have multiple slot outlets in a single component. For example, in a component with the following template: template < div class = "container" > < header > < main > < footer > For these cases, the element has a special attribute, name , which can be used to assign a unique ID to different slots so you can determine where content should be rendered: template < div class = "container" > < header > < slot name = "header" > < main > < slot > < footer > < slot name = "footer" > A outlet without name implicitly has the name "default". In a parent component using , we need a way to pass multiple slot content fragments, each targeting a different slot outlet. This is where named slots come in. To pass a named slot, we need to use a
