has_children on categories

[robsonsobral]

Is your feature request related to a problem? Please describe.

We can find the categories which has parents, but not the ones which are parents.

A sample of the code I need:

{exp:channel:categories channel="news" style="nested" show_empty="no"}
    <a href="{path='channel/index'}">{category_name}</a>

    {if has_children}
        <button
            type="button"
            aria-haspopup="true"
        >children categories</button>
    {/if}
{/exp:channel:categories}

Describe the solution you'd like

We could have a has_children conditional on exp:category_archive and exp:categories.

Describe alternatives you've considered

The only other solution is to use custom queries.

• I am capable and would like to work on implementation of this feature if it is considered.
