Dynamic DCT

abhishek_gupta

Hi,

I have to make a dynamic DCT. Dynamic in the sense that when the user selects a value from a drop-down, the rest of the DCT should be populated automatically according to the selection in the drop down.

Citing an example. I have 3 values in the dropdown, a,b and c. When the user selects 'a', 2 text boxes of replicants should get shown up automatically below the drop down. Then when I go to the same drop down at the top, and select b, a textarea comes up below. And when I select 'c' in the same dropdown above, a text boxe and a textarea shows below.

Is there any way to do this. I presume this can be done via FormAPI, but am not to sure if it can be done thru simple templating.

Thanks for the help in advance.

This is exactly the sort of thing that FormAPI was created for. Not sure what you mean by "simple templating" but if you're asking if it can be done without FormAPI, I'd have to say the answer is no.

With FormAPI, it's pretty straightforward. Simply define all of the elements in your datacapture.cfg and then use an onChange event handler to hide/show things based on the value in your dropdown. I believe that some of the examples shipped with FormAPI will be of assistance.

Thanks for the prompt reply.

Well by simple templating I just meant, without using any of the formapi stuff.

Well, so I understand this has to be done by Formapi and there's no other way. I'll have to have a look at the FormApi examples.

But if I want to click on the plus sign of the replicant, and a small select box appears, where I can just select the option I want and then the corresponding text boxes would appear below. Can this be done without formapi?

Thanks,
Abhi

Look at the documentation of the <container> tag with <or>.
You can have something like
<container... combination="or">
<item 1 ...>
<item 2 ...>
</container>

When you click the + sign, you can choose whether to add item 1 or item 2. I think that might solve your problem ?
