How to insert extra item to template each

Question

I have such template

<tbody>
  {{#each topics as |topic|}}
    {{topic-list-item topic=topic}}
  {{/each}}
</tbody>

I want to insert extra item into this rendering template list, something like this:

<tbody>
  {{#each topics as |topic|}}
    {{#if someCondition}}
      {{my-list-item}}
    {{else}}
      {{topic-list-item topic=topic}}
    {{/if}}
  {{/each}}
</tbody>

But the problem is this solution will skip some topic when someCondition is true, ie it will note insert but replace.

Is there a solution to add an item to template render list?

UPDATE: I want to insert {{my-list-item}} only once into render list if someCondition is true

Answer 1

If you want to dislay topic-list-item all the time irrespective of condition then, you can do it by removing else.

<tbody>
      {{#each topics as |topic|}}
        {{#if someCondition}}
          {{my-list-item}}
        {{/if}}
        {{topic-list-item topic=topic}}        
      {{/each}}
    </tbody>
