For more options please refer to the Ember Power Select docs.

Control if create option should be shown

You can provide a callback showCreateWhen, which will be called whenever the user types into the search field. If you return true, the create option will be shown. If you return false, it won't be shown.

<PowerSelectWithCreate
  @options={{countries}}
  @searchField="name"
  @selected={{selectedCountry}}
  @onCreate={{action "createCountry"}}
  @showCreateWhen={{action "hideCreateOptionOnSameName"}}
  as |country|
>
  {{country.name}}
</PowerSelectWithCreate>

import Component from '@ember/component';
import { action } from '@ember/object';

export default class MyComponent extends Component {
  @action
  hideCreateOptionOnSameName(term) {
    let existingOption = this.countries.find(({ name }) => name === term);
    return !existingOption;
  }
}

Control create option position

You can provide showCreatePosition property to control the position(bottom|top) of create option. It should be either "top" or "bottom". It defaults to "top".

<PowerSelectWithCreate
  @options={{countries}}
  @searchField="name"
  @selected={{selectedCountry}}
  @onCreate={{action "createCountry"}}
  @showCreatePosition="bottom"
  @showCreateWhen={{action "hideCreateOptionOnSameName"}}
  as |country|
>
  {{country.name}}
</PowerSelectWithCreate>

Control the create option's label - Default Add "{{option}}"...

You can provide the buildSuggestion action to control the label of the create option. Default - Add "{{option}}"...

<PowerSelectWithCreate
  @options={{countries}}
  @searchField="name"
  @selected={{selectedCountry}}
  @onCreate={{action "createCountry"}}
  @buildSuggestion={{action "customSuggestion"}}
>
  {{country.name}}
</PowerSelectWithCreate>

import Component from '@ember/component';
import { action } from '@ember/object';

export default class MyComponent extends Component {
  @action
  customSuggestion(term) {
    return `Create ${term}`;
  }
}

Pass the creation option to a component for more control

Beyond building the suggestion label, you can pass the suggestedOptionComponent property, which should be a component, not a string to be embroider compatible.

This component will receive the suggestedOption itself as option and the current term as term.

<PowerSelectWithCreate
  @options={{countries}}
  @searchField="name"
  @selected={{selectedCountry}}
  @onCreate={{action "createCountry"}}
  @suggestedOptionComponent={{component (ensure-safe-component "suggested-option")}}
>
  {{country.name}}
</PowerSelectWithCreate>

<span class="is-suggested">
  Add "{{term}}"...
</span>
