What are you trying to achieve:
I want the form to directly save to collection. I dont mind using Velo also.
What have you already tried:
I have zero clue on the velo, hence no idea where to start.
Hi, @Smit_Shah !!
If your goal is simply to “save data to a specific collection,” then you can probably achieve it easily using a basic API like the one below. Rather than relying on Wix’s built-in concept of forms, you can just set up a text element and a submit button yourself—and that alone already functions as a form. From there, you only need to write some code so that when the button is clicked, the content of the text input is saved to a specific collection. That should be enough to get the core functionality working. 
The only other thing you might need is input validation to make sure the submitted content is in the correct format. I can’t say this with absolute certainty since I haven’t checked your specific setup, but even if you already have a pre-built form, it’s very likely that you can modify just the submit button to save data to your chosen collection. And even if you can’t reuse your existing form, creating everything from scratch as described above should still be enough to achieve what you need!

In fact…
You don’t need to write any code at all, you can simply use a dataset and link the input fields to their respective columns in your CMS and your form is ready.
You don’t need any Velo for this. Here’s a tutorial by the amazing @thewixwiz where you can learn how to create a custom form in just a few minutes!
Awesome. Thanks. Can I know the member email address ? So that It can be auto filled.. instead of me asking the member to rekey in ?
For that you will have to use some Velo.
Here’s a starting point. Tweak it to your requirements:
