Cordless blinds are blinds where the control cords, or pull cords, are removed in favour of another system. An example of this would be a 'sprung-loaded' or 'tensioned' roller blind
Another example is chainless-weights on Vertical Blind
s; where you would traditionally have link chains connecting the slats/panels at the bottom, there is an option to choose 'free-weights', or 'encapsulated-weights'. These are either sealed in, or hang freely in the bottom pocket.
