disallow use v-if on the same element as v-for (vue/no-use-v-if-with-v-for)

⚙️ This rule is included in all of "plugin:vue/essential", "plugin:vue/strongly-recommended" and "plugin:vue/recommended".

Never use v-if on the same element as v-for.

There are two common cases where this can be tempting:

To filter items in a list (e.g. v-for="user in users" v-if="user.isActive"). In these cases, replace users with a new computed property that returns your filtered list (e.g. activeUsers).

To avoid rendering a list if it should be hidden (e.g. v-for="user in users" v-if="shouldShowUsers"). In these cases, move the v-if to a container element (e.g. ul, ol).

📖 Rule Details

👎 Examples of incorrect code for this rule:

<TodoItem
  v-if="complete"
  v-for="todo in todos"
  :todo="todo"
/>

In this case, the v-if should be written on the wrapper element.

<TodoItem
  v-for="todo in todos"
  v-if="todo.shown"
  :todo="todo"
/>

In this case, the v-for list variable should be replace with a computed property that returns your filtered list.

<ul v-if="complete">
  <TodoItem
    v-for="todo in todos"

</ul>
