Drop downs are not remaining open

Hi ! I am having an issue with my drop downs in this page,


When I click on any of the drop downs, the other drop down links hide, also I can´t seem to manage how to set the drop downs to remain open until the user decides to close them again.

Please help !! Thankyou so much !
