Late to reply here, you might have already discovered this:
1) using the left mouse, draw a box around the group and let go of the mouse key
2) it will start moving the components DISCONNECTED
3a) hit the TAB key on your keyboard, it will keep the wire CONNECTED now
or
3b) right click and get the context menu, choose Drag Block
TAB is the hotkey for Drag Block when in Block Select mode.
It also doesn't make any attempt to keep your dragged wires looking nice
