Built In Closet Drawer Question

Hello all,

I wanted to have some input from the much more knowledgeable. I am working on a walk-in closet. I am wanting to build a drawer and shelf unit. A unit about 24”wide and 7 feet tall. The bottom half will be drawers and the top half will be shelves. There will be a horizontal divider between the shelf area and the drawers. However I was wondering if drawer portion needs more horizontal dividers or web frame in between the drawers like a stand alone unit would.

Thank you
Lenny
