[Plugin: Events Manager] How to add Event Attribute Field in the Search form ?

Hello everybody,

I just tested “Events Manager plugin” for the first time and I find it fantastic ! I just have one question. It’s easy to create Event Attributes (with a selecting box / #_ATT{key}{option 1|option 2|option 3|etc.} ) but how to add this new field as filter in the EM search form ?

thanks so much for your help ??
