Hi! How to make so that when typing in the line search bar, listing the found matches stood out in bold?
Is it javascript itself to write a third-party function or is there a built-in property? I didn’t find that property.

There is not something like this built-in, you need to implement it manually

Thanks. I approximately and thought, but just in case, asked not to write too much code.
