Prepend (Beta)

`slot.prepend(component)`

Add a component instance as the first child of the slot.

Only component instances can be added to slots. Components from installed libraries are not supported; only components in the site’s own component library can be added to a slot. This action is undoable via the Designer’s undo stack.

Beta

These methods are in public beta and may change with future releases.

Syntax

1 slot.prepend(component: Component): Promise<null>

Parameters

component: Component — The component definition to instantiate and insert at the beginning of the slot.

Returns

Promise<null>

A Promise that resolves when the component instance is added.

Example

1 // Get a component instance on the page
2 const elements = await webflow.getAllElements();
3 const componentInstance = elements.find(el => el.type === 'ComponentInstance');
4 
5 if (componentInstance?.type === 'ComponentInstance') {
6 
7   // Get the first slot on the instance
8   const slots = await componentInstance.getSlots();
9   const firstSlot = slots[0];
10 
11   if (firstSlot) {
12 
13     // Find the component to add
14     const components = await webflow.getAllComponents();
15     const cardComponent = await webflow.getComponentByName('Card');
16 
17     if (cardComponent) {
18 
19       // Prepend a component instance to the slot
20       await firstSlot.prepend(cardComponent);
21 
22     }
23   }
24 
25 } else {
26   console.log('No component instance found');
27 }
