Nette\Forms – Dependent select box

Hello,

I have a one questions on Nette\Forms.

I have ajax form with dependent select boxes and I need show same form with selected data after being form send.

Form serves as a filter and always occupy the same field is annoying.

I use this tutorial https://blog.nette.org/…-and-pure-js.

Can I save all ajax requests from form and after being send set as default? Or is this idea totally wrong?

Thank you for reading and for any advice
