I want to build my own extension that filters data. I.e. it has a date input of some kind the user sets, and then in turn tells the data give me stuff where col_date = myDateVar. Are there any tutorials on something similar?
So I was looking at one, a date picker specifically. But I'm not really unclear on how I tell qlick, here is the date, filter the data for me. Is there any way you could point me in the right direction?
