Hi all again! :)

I don't know if this is strcit a BEM question. Can I reuse just some parts of blocks?. Is a copy+paste thing and I think it's not a good idea.. :S

With this block

<div class="newsletter">
    <div class="newsletter__title">Newsletter</div>
    <div class="newsletter__subtitle">This is the newsletter subtitle</div>
</div>

Can I use just this in other parts of the interface:

<div class="newsletter">
    <div class="newsletter__title">Newsletter</div>
</div>

Or I need to create for example a modifier like newsletter--no-subtitle and hide it

<div class="newsletter newsletter--no-subtitle">
    <div class="newsletter__title">Newsletter</div>
    <div class="newsletter__subtitle">This is the newsletter subtitle</div>
</div>

Thanks you!!
