Controlling field: Country

Options:
1. US
2. UK

Target field #1: City

If Country=US, then
1. NYC
2. LA
If Country=UK, then
1. London
2. Manchester

Target field #2: Landscape

If Country=US, then
1. Empire State Building
2. Time Square
If Country=UK, then
1. Big Ben
2. London Eye

So, I want to make Country field controls both City and Landscape fields w.

I've tried the tutorial http://www.chronoengine.com/faqs/70-cfv5/5232-how-do-i-build-a-dynamic-drop-down-in-cfv5.html
And filled in the fields like these:

On=US
Set Options City
NYC=NYC
LA=LA

On=US
Set Options Landscape
Empire State Building=Empire State Building
Time Square=Time Square

But it crashed my form instead...😟
Please help! Thank you in advance...

Hi,

How did it crash your form ?

Thank you for your response.

My form just stopped working properly.
The features of all other fields just disappeared. Even the "required" validations also vanished.

Cmiiw, but I guess it is because the event defined for controlling fields can not be set more than once. Like what I did, I can't set the event of US for City and Landscape options simultaneously. When I removed the Landscape options (leaving only one set options for US), the form recovered.

There is no reason for the config to be lost when the same event is set more than once, if you can supply some screenshots then this may help us understand the problem better.

I was surprised when I worked with my Joomla this morning, a strange advert popped up from my window.
From there I wonder if my computer got attacked by a virus. And yes, when I tried to construct the form with another computer (protected by Kaspersky), the form worked like a charm.
Sorry for having added a silly enquiry in this forum. I am good now.
Thank you for this amazing extension.

I have just figured one important thing.
The dynamic feature won't work if apostrophe is used in the options list/ajax event. It even crashes the form.

Hi adhynagara2,

Quotes are best avoided in strings like options because they can cause odd problems that are hard to find. If they are needed you can usually get them to work using an escape character e.g. \' or an HTML Entity e.g. ’
