Use simple HTML link as input for conditional logic

I would like to create a simple "learn more" HTML link to show/hide the description of an item, similar to Apple.com order page for each configurable item.

What gravity form has allowed me to do (out of the box) is already very close and I can achieve similar function by using a single "check box" and an HTML description field with conditional logic which uses the check box as input.

However, instead of a check box, I would like to use a simple "link" which acts as input to the HTML description field.

Is this possible? Could you suggest other ways to accomplish this? Thank you for the support.

Hi Kevin,
Thanks for the reference. I am a novice in web programming so pardon my questions if these seemed to be too basic:

1. I copied and pasted part of the code from the example into an "HTML block" in gravity form.
here is the part that i copied:

<style>
p { width:400px; }
</style>
<script src="http://code.jquery.com/jquery-1.5.js"></script>
<button>Toggle</button>

<p>
This is the paragraph to end all paragraphs. You
should feel lucky to have seen such a paragraph in
your life. Congratulations!
</p>
<script>
$("button").click(function () {
$("p").slideToggle("slow");
});
</script>

2. The "toggle" button shows up in the form just like in the example of jQuery page
3. However, when I clicked the "toggle" button, somehow it caused a reloading of the page and it caused the "submit" to be actuated because the next thing I see, many of the required field were marked red as if I just clicked the "submit" button

Can you provide more pointers on how to incorporate this show/hide feature? I can see it almost working...
Thanks for the support.

Hi Carl,

Thanks for the clarification. Initially, I was hoping to tap into the existing functionality of gravity forms. Because the toggle function with panel slide in/out can already be accomplished with conditional logic + animation, both features are built in to gravity forms.
The thing that I notice differently between "html block" in gravity form and other types such as "multiple choices" is that "html block" does not provide a defined "value" to other elements in the form, therefore could not be used as an input to the subsequent element to be used with conditional logic. But if "onclick" on an URL or something similar along that line can be used, then it maybe possible-just a thought.
If a simple customization is possible, I would love to learn about it from you guys. Thanks for the support.
