Attaching Form widget into a Window footer


I want to put some form elements (buttons, checkbox and select) into a Window’s footer. In the body of Windows is a Tabbar with a Form and a Grid

This code didnt give error, but insteed the checkbox, appearing a button-like thing.{
name: “checkbox”,
type: “checkbox”,
text: “I agree”,
label: “”,
value: “checkboxvalue”

I made a Form with necesary elements, but I didnt know, how can attach into the Window’s footer.

Can help me Someone?

Thanks and Cheers!

Only the controls of the dhx.Toolbar can be used in the footer of a dhx.Window:
