Add optional JSON parameters

[damienborgniet]

I'm actually using FCBK Plugin and I need to disting elements show when typing with an optionnal parameters. Actually the array is [key:xxx, value:xxx] and I want to make this : [key:xxx, value:xxx, isblue: (true/false)]. I check if isblue is true when I add element on ul (dropdown list) and add a class if it is.

I tried to modify plugin but it seems doesn't works, wich lines or function must I change for make this ?

PS : Sorry for my english
