It can contain a template fragment, which is rendered based on the value of a dynamic property, such as v-if or $slots. A named slot can also be a container for child components. Often, template v-slot:header> is shorthand for template #slot:header>. For example, template v-slot:header>=”Hello world”>. See Rendering and Using Slots for more information.
