Custom Scrollbar Support

• I have searched the issues of this repository and believe that this is not a duplicate.

Expected Behavior

I would love either native support for custom scrollbars or some guidance on how to get at components buried within other components (such as the <Menu> component within a <Select> component) to add external custom scrollbars.

Current Behavior

Currently, after searching the issues, there doesn’t seem to be any talk about using custom scrollbars. (sorry if I missed it, I looked through about 4 pages) I am unable to find a way to wrap the <Menu> called from <Select> in my own custom scrollbar component.

Steps to Reproduce (for bugs)

1. Use <Select> with a fixed height menu and notice that it uses the browsers default scrollbar. For example, the Multiple Select demo.

Context

I have been able to wrap other Material-UI components in my custom scrollbar, but I am unable to get at components called from other components, such as <Select>, so some of my elements have custom scrollbars and others do not.

Your Environment

Tech	Version
Material-UI	beta.27
React	15
browser	chrome
OS	OS X

Could you rather add custom scrollbar support to the theme as ideally all scrollbars across all components that need scrolling should use the same custom scrollbar solution. This should not be for advanced users as scrollbars on desktop platforms are bulky and do not fit in at all with the material theme.

Great! For anyone else looking to do custom scrollbars, on our project we’re using react-custom-scrollbars. It works as expected and is easy to use.

The problem is that it needs to wrap components to work. So for example…

<MenuList>
    <Scrollbar>
        {this.renderOptions()}
    </Scrollbar>
</MenuList>

This works great on it’s own and we are using it in conjunction with the <Popover> component. The problem comes in when we don’t have access to wrap the <MenuItems> or similar components without disrupting the function of the component. For example…

<Select {...whateverProps}>
    <Scrollbar>
        {months.map((month: string, i: number) => (
            <MenuItem key={month} value={i}>
                {month}
             </MenuItem>
        ))}
    <Scrollbar />
</Select>

Trying to insert <Scrollbar> in here doesn’t work and it seems wrapping the <MenuItems> with anything breaks the <Select>. Here is an image showing the comparison of not wrapped vs wrapped.

A guide/documentation from better coders than I would be awesome and hopefully useful to the community.

Thanks!
