To have a dropdown for your own team copy over all of the content below. It might be needed to adjust a thing or two. Comments have been added throughout the code what must be changed.

Inspirational websites:

[http://javascript-array.com/scripts/simple_drop_down_menu/ Most basic dropdown menu, with no submenu's]
[http://jquery.com/ The javascript library used to add effects and optimise the dropdown]
[http://www.tyssendesign.com.au/articles/css/centering-a-dropdown-menu/ How to center a ul list effectively]

The dropdown has been created and developed by the KULeuven team.

Inverter

Position in the system

The inverter part receives its input from the filter, T7. The inverter's function is to produce HSL when no light is present, so a low T7 input gives rise to a high HSL output and vice versa. A high output of HSL will be used in the cell death part to produce CcdB, meaning that the cell will start a timer and eventually die off if no light remains present.
