How to condition an attribute in vue?

Question

Vue.js

I can add a condition for a normal attribute that doesn't need to be sent to . But if I need to pass something to that attribute, I can't do it.
<input :required="cojndition">

<b-field label="Error" type="is-danger">
      <b-input placeholder="Error"></b-input>
    </b-field>

I need to put a condition on type

Answer 1

:type="condition ? 'is-danger' : undefined" well, or better to take out the computed property.
