Due to bundle size and complexity constraints, we can't include all the possible modifiers in the core library, but we do encourage everybody to publish their own custom modifiers in dedicated npm packages!
They are small and unobtrusive.
Alternatively, consider to support us on Open Collective!
You can find all the information needed to learn how to create your very own custom modifiers by visiting the dedicated docs.
Below you can find a few common examples to help get you started:
maxSizemodifier: changes the size of your popper to fit it within the available viewport space. (published as an npm package)
sameWidthmodifier: make your popper the same width as the reference.
