focus-trap-vue Build Status npm package thanks

Vue component to trap the focus within a DOM element


For Vue 2

npm install focus-trap focus-trap-vue@legacy

 For Vue 3

npm install focus-trap focus-trap-vue


This library exports one single named export FocusTrap and requires focus-trap as a peer dependency. So you can locally import the component or declare it globally:

 Register globally in a Vue 2 app

import { FocusTrap } from 'focus-trap-vue'

Vue.component('FocusTrap', FocusTrap)

 Register globally in a Vue 3 app

import { FocusTrap } from 'focus-trap-vue'

  .component('FocusTrap', FocusTrap)

Note this documentation is for Vue 3 and some props/events might not exist in the Vue 2 version

FocusTrap can be controlled in three different ways:

  • by using the active Boolean prop
  • by using v-model:active (uses the active prop, Vue 3 only)
  • by calling the activate/deactivate method on the component

The recommended approach is using v-model:active and it should contain one single child:

<focus-trap v-model:active="isActive">
  <modal-dialog tabindex="-1">
    <p>Do you accept the cookies?</p>
    <button @click="acceptCookies">Yes</button>
    <button @click="isActive = false">No</button>

When isActive becomes true, it activates the focus trap. By default it sets the focus to its child, so make sure the element is a focusable element. If it's not you wil need to give it the tabindex="-1" attribute. You can also customize the initial element focused. This element should be an element that the user can interact with. For example, an input. It's a good practice to always focus an interactable element instead of the modal container:

<focus-trap v-model:active="isActive" :initial-focus="() => $refs.nameInput">
    <p>What name do you want to use?</p>
    <form @submit.prevent="setName">
        New Name
        <input ref="nameInput" />
      <button>Change name</button>


FocusTrap also accepts other props:

  • escapeDeactivates: boolean
  • returnFocusOnDeactivate: boolean
  • allowOutsideClick: boolean | ((e: MouseEvent | TouchEvent) => boolean)
  • clickOutsideDeactivates: boolean | ((e: MouseEvent | TouchEvent) => boolean)
  • initialFocus: string | (() => Element) Selector or function returning an Element
  • fallbackFocus: string | (() => Element) Selector or function returning an Element
  • delayInitialFocus: boolean
  • tabbableOptions: FocusTrapTabbableOptions Options passed to tabbableOptions

Please, refer to focus-trap documentation to know what they do.


FocusTrap emits 2 events. They are in-sync with the prop active

  • activate: Whenever the trap activates
  • deactivate: Whenever the trap deactivates (note it can also be deactivated by pressing Esc or clicking outside)


FocusTrap can be used without v-model:active. In that case, you will use the methods and probably need to initialize the trap as deactivated, otherwise, the focus will start as active:

<button @click="() => $refs.focusTrap.activate()">Show the modal</button>

<focus-trap :active="false" ref="focusTrap">
    <p>Hello there!</p>
    <button @click="() => $refs.focusTrap.deactivate()">Okay...</button>

Note the use of arrow functions, this is necessary because we are accessing $refs which are unset on first render.
