Create a custom checkbox component

[Mateus Lucio dos Santos]

Hi!
I need to display a checkbox in a webpage. This checkbox work as a node 
in a treeview, so i need to save in the checkbox tag which node is his 
parent and which node are his children.

I tried to simply add two attributes to the checkbox tag like this 
<input id="test" type="checkbox" parent="parent" children="children" /> 
it works just fine in I.E but firefox doesn't recognize the parent and 
children attributes, thats why i'm trying to solve this creating a 
component that has those attributes.

I'm a beginner using tapestry so i'm clueless about how to create a 
component that works the this way.
Can any one send me some material or explain me how to create this 
component?

Thanks in advance
