Taking out a # of Mats from the bank
Take them all out into personal inventory then Alt-drag with mouse – that brings up a split option window. The spliting has to happen in the inventory pane (i) not the bank pane.
For some reason it never works for me while the stack is in a bank slot.

You can alt drag between bank slots and also from bank/collection slots to inventory. It doesn’t have to be taken out of the bank first. This is assuming you mean your personal bank and not the guild bank. For the guild bank you have to move the items into your inventory first if you want to stack or split.
