Re: AJAX Chain Reaction - Multiple Divs.

Good to hear!

At the moment, you initially only display one <select> list, and then
based on that, you show other <select> lists. But what you want, is to
show all the lists always, and just change the options available, the
<label> of the lists, and potentially hide some lists. Does that sound
accurate?

I think I may have confused myself a little here as well!

Each time a select box is changed, cakePHP will detect which step it requires from the user next. I will give you two examples:

Example 1 - Selecting a vertical blind (just the louvres, 89mm wide in Lino Ivory from the Fabric Box collection)

Step 1) Type of Blind: Vertical
Step 2) Fabric Book: Fabric Box
Step 3) Specification: Vanes Only
Step 4) Louvre Width: 89mm
Step 5) Fabric: Lino Ivory

Example 2 - Selecting a perfect fit pleated blind in an Aura White fabric.

Step 1) Type of Blind: Pleated
Step 2) Specification: Perfect Fit
Step 3) Fabric: Aura White

This is why I decided to show and hide select boxes.

If I selected the first example of a vertical blind all the way to Fabric, but then I changed my mind and changed "Type of Blind" to "Pleated", all the other 4 steps need to disappear and step 2 then becomes "Specification". What I have been asked to do now this system is working as intended... to make it even easier for the user! Heh :)

I need to define a default path for each type of blind - i.e. the most common product selection - or the product selection which comes at no extra charge to the user.

A vertical blind would be automatically selected like the following when you specify "Type of Blind" as vertical:
1. Vertical
2. Blindtex Seasons
3. Full Vertical
4. 89mm
5. "Please Select"

The approach you would need to take I think would be one where instead
of making an AJAX request and the response being an HTML snippet which
you insert into a <div>, you need to make an AJAX request with the
response being JSON data, which you supply to a function which
constructs the <option>s for you and attaches them to the appropriate
<select> element. This way, your <select> elements could be defined
statically, and hence appear on the form from the first page load.

I have heard of JSON but frustratingly I haven't used it yet, it is on my todo list so why not start now?
 

Does it sound like I'm on the right track? If so, I can provide you
with a small example on how to achieve this.

Would you be as kind?

Here's some example code (it's not too pretty, but it does the job)

As you can see, I don't just need to generate the select lists, but I also need to execute the controller actions one after another.

P.S. the drop down boxes were provided for me to use, I will find out if they are proprietary or not.

Kind Regards
