[cf5] create 3 linked dropdown with dynamic data inside

Hello i search a system to create 3 fields (dropdown and radio field) how are linked
=> first field is a drop down where an sql request (to find k2 category list)
=> second field is a drop down where an sql request (to find k2 sub-category list in regard of first field)
=> third field is a drop down where an sql request (to find k2 items list in regard of category in second field)
all in ajax mode
Can you guide me ?
regards

Hi micker,
​
You can do this in v6 or better start with v7RC1 directly, both can be installed on the same site with v5
​
The first dropdown will get the options from a Read Data, the 2nd will listen to changes in the first dropdown and reload, same for the 3rd
​
I can prepare a demo form in v7 based on the Joomla categories and content tables!
​
Best regards

oh cooool i can be very interested by this demo !

hello any news about this ?
or i need to find how to update 4 dropdowns element
i found this https://www.youtube.com/watch?v=7-JX1Ze0SEk
with this first dropdown update second but not third...
any idea ?

I have demo form ready for v7 with 2 dropdowns, but an update will be needed for it to work for you, you may send me a message using the contact page to get the latest updated files!
​
But in general, 2 dropdowns are like 3, you setup each dropdown to reload when the previous one changes!

message sended thanks

the new update is now available for download and the demo form for connected dropdowns is included!

thanks i am testing it ... very impressive
sorry i discove v7 version .. i didn't find where i can change data sources ? (i want to use it with k2)
its realy cool

Data Sources are actions, so first add an action "Read data" then you will be able to find it in the data sources list!
