  We investigate the dynamic asymptotic dimension for \'etale groupoids
introduced by Guentner, Willett and Yu. In particular, we establish several
permanence properties, including estimates for products and unions of
groupoids. We also establish invariance of the dynamic asymptotic dimension
under Morita equivalence. In the second part of the article, we consider a
canonical coarse structure on an \'etale groupoid and compare the asymptotic
dimension of the resulting coarse space with the dynamic asymptotic dimension
of the underlying groupoid.
