Hey,
thank you very much for all the work you have put into this lib. It is really awesome to use.

I build a tool to have users create their task 'graphically', start it and have a nice progress view of the state.
In my input form I need to dynamically add or remove elements from the form.
For example if the user selects 'element A' in a dropdown he should see checkboxes 1,2,3 and if he selects 'element B' in the dropdown he should see checkboxes 4,5,6,7.
In a future version this should even be fed from a api call.

The only way I currently see this working is have a parameter in my func to create the form and adding either checkboxes, then in the selected func of the dropdown create a new form and set the current root to the new form. Basically the form itself creates a new version of it self and overwrites itself.
This feels very convoluted and just not right, is there a better way?

Thanks @frenos. I believe that is currently the only solution.

Would adding methods such as Form.HideFormItem(p Primitive) and Form.ShowFormItem(p Primitive) make the most sense? Or perhaps you have something else in mind?

Yes, I think that should work well. Thank you.
