    ...
  </div>
</div>

Options

• sticky-offset - set sticky offset, it support a vm variable name or a js expression like {top: 10, bottom: 20}
  • top(number) - set the top breakpoint (default: 0)
  • bottom(number) - set the bottom breakpoint (default: 0)
• sticky-side(string) - decide which side should be sticky, you can set top、bottom or both (default: top)
• sticky-z-index (number) - to set the z-index of element to stick
• on-stick (function) - callback when sticky and release, receiveing 1 argument with object indicating the state, like:

// The element is sticked on top
{
  bottom: false,
  top: true,
  sticked: true

An expression that evaluates to false set on v-sticky can be used to disable stickiness conditionally.

<div sticky-container>
  <div v-sticky="shouldStick">
    ...
  </div>
</div>

import { defineComponent, ref } from 'vue'

// Options API
defineComponent({
  data() {
    shouldStick: false
  }
})

// or with the Composition API
defineComponent({
  setup() {
    const shouldStick = ref(false)

    return { shouldStick }
  }
})
