Draggable Elements

Draggable elements give you the ability to move, resize and rotate elements by dragging them with the mouse. This is useful for creating floating elements in your slides.

Directive Usage

Data from the frontmatter

---
dragPos:
  square: Left,Top,Width,Height,Rotate
---

<img v-drag="'square'" src="https://sli.dev/logo.png">

Data from the directive value

WARNING

Slidev use regex to update the position value in the slide content. If you meet problems, please use the frontmatter to define the values instead.

<img v-drag="[Left,Top,Width,Height,Rotate]" src="https://sli.dev/logo.png">

Component Usage

Data from the frontmatter

---
dragPos:
  foo: Left,Top,Width,Height,Rotate
---

<v-drag pos="foo" text-3xl>
  <carbon:arrow-up />
  Use the `v-drag` component to have a draggable container!
</v-drag>

Data from props

<v-drag pos="Left,Top,Width,Height,Rotate" text-3xl>
  <carbon:arrow-up />
  Use the `v-drag` component to have a draggable container!
</v-drag>

Automatic Height

You can set Height to NaN (if you use the directive) or _ (if you use the component) to make the height of the draggable element automatically adjust to its content.

Create a Draggable Element

When you first create a draggable element, you don't need to specify the position value (but you need to specify the position name if you want to use the frontmatter). Slidev will automatically generate the initial position value for you.

Controls

• Double click the draggable element to start dragging it.
• You can also use the arrow keys to move the element.
• Hold Shift while dragging to preserve its aspect ratio.
• Click outside the draggable element to stop dragging it.
