@Playalot There's a thread on this
here.
The answers given there are:
There is a tiny triangle at the top left corner of the stack. Click it to open the stack. From there, you can click, hold and drag as many of the individual items as you want. Click, hold and drag the triangle itself to move the entire stack from one location to another (say, from personal inventory to the refrigerator).
Hold down shift when you click on the triangle and drag it to the Sim you want to have the item. Then a window will appear that looks like the one to give a nooboo it's name. Just say the number of the item you want them to have and voila!
