Set selector for specific editable div

Hi dude.

I install Classic Editor Pluggin, write a post like above:

Eloquent settings

Post content selector DIV.editable-box

and in my post i put something like this.

<div class=”editable-box”>
Lorem ipsum something else
</div>

<div class”just-another-class”>
Lorem ipsum and more…
</div>

<p>Lorem Ipsum… </p>

When I go to the post and when i clic on blue pen, appear double content, and only <p>content</p> can be editable.

but if I hold shift higligh right div. But cant edit.

I would like to have one specific editable box.
<div class=”editable”>Lorem Ipsum editable content</div>

It is possible?

Thank you for you work! it is awesome.
