slick-columnpicker remains in DOM after destroy

I have a slickgrid for editing. After i call destroy method i see slick-columnpicker spans (count is equal to column count of detached slickgrid instance) in DOM nested to body.
I wanted to remove them by jquery but no id was injected to spans, so when multiple instances exist in DOM it will be a problem. Please attach grid's id to spans.

And i also want to be able to disable selectable columns feature. I dont need it. I removed slick.columnpicker.js from injected scripts but slick grid didnt work. What i am missing.

But although some problems, Thank you for this great grid. Congratulations man! It is really awesome...

The column picker component wasn't being destroyed. It didn't actually have a destroy() method, so I added one.

No idea what you mean about disabling the selectable columns feature. Do you mean that from the column picker you just want to use the two option checkboxes at the bottom? If so, that's not a typical use case, and the column picker doesn't support it. That being said, this component is just a sample, and you can easily write your own one that suits your needs better based on it.
