How to add a grid in a form

[MTi]

Hello!

I have a form in which I input data such as name, age and so on...
I also would like to have a field in the from that looks like a drop down box but its content would be a single Icon.

If the user opens the box, a grid would appear allowing the user to select another icon (some kind of icon picker component).

I did not find any standard way to do this and so I came to the conclusion that a custom component needs to be added.

So far, my form is built from resource files and I have to say that I have no idea how I could make that custom component and integrate it within the code of the form and the related resource file.

I guess someone out there has had similar issues and I hope I could get some help as to how to proceed to achieve my form.

Thanks in advance for your help.
