I have a client with a real estate site and we just started using IDX broker. IDX broker uses prototype.js which breaks the mootools dropdown menu (fusion). Does anyone know of a fix, or a different drop down menu solution for 2.5 that won't be in conflict with prototype.js?
You should really ask that question in that 3rd party extension support and not here. Also, please check JED for a suitable menu replacement if you think that this will solve your issue but I would try solve this with IDX broker support first
