Hi Deli2710,
custom development isn’t anything that works through an option. If you’re familiar with coding, you would need to code a custom child theme and then code a custom version of the widget with your preferred modifications within the child theme.
In case you’re not familiar with coding, you could hire a developer or freelancer for custom development (e.g. through Codeable).
Yes, I understand. I create a file with custom widget (I copy this from Your old one and custom some lines), but how I register this widget or find it in widgets offer?
Can You help me?
As mentioned, you would need to code your own custom child theme or plugin and then register your new custom widget within the child theme or plugin. Please understand that we can’t assist with custom development.
However, here you can find some additional information that might be helpful (if you’re familiar with coding):
