# vue/require-toggle-inside-transition

> require control the display of the content inside `<transition>`

## :book: Rule Details

This rule reports elements inside `<transition>` that do not control the display.

<eslint-code-block :rules="{'vue/require-toggle-inside-transition': ['error']}">

```vue
<template>
  <!-- ✓ GOOD -->
  <transition><div v-if="show" /></transition>
  <transition><div v-show="show" /></transition>

  <!-- ✗ BAD -->
  <transition><div /></transition>
</template>
```

</eslint-code-block>

## :wrench: Options

```json
{
  "vue/require-toggle-inside-transition": ["error", {
    "additionalDirectives": []
  }]
}
```

- `additionalDirectives` (`string[]`) ... Custom directives which will satisfy this rule in addition to `v-show` and `v-if`. Should be added without the `v-` prefix.

### `additionalDirectives: ["dialog"]`

<eslint-code-block :rules="{'vue/require-toggle-inside-transition': ['error', {additionalDirectives: ['dialog']}]}">

```vue
<template>
  <!-- ✓ GOOD -->
  <transition><div v-if="show" /></transition>
  <transition><div v-show="show" /></transition>
  <transition><dialog v-dialog="show" /></transition>

  <!-- ✗ BAD -->
  <transition><div /></transition>
  <transition><div v-custom="show" /></transition>
<template>
```

</eslint-code-block>
