Hi!
After downloading of theme “Ildy” I found that I can’t customize my theme like on your Demo 
What’s wrong?((
Help!

Hello there,
I hope you are doing well today.
Please ensure that you have installed the Illdy companion plugin via Appearance > About Illdy > Recommended Plugins. This plugin has addition widgets that are used in the theme.
Best Regards,
Support
