[DatePicker] Misc TODO

[oliviertassinari]

Considering that the quality of the documentation is the number 1 factor developers has shared that they would consider when picking a UI library in our latest survey, I think that it worth starting a list of what we want to document/improve in the picker pages as we move:

• https://material-ui-pickers.dev/demo/datepicker to https://material-ui.com/components/date-picker/
• https://material-ui-pickers.dev/demo/timepicker to https://material-ui.com/components/time-picker/
• and so on.

Items I have noticed so far:

• Have the demos work in isolation The demos should work in isolation material-ui-pickers#1650.
• Add a customization example. Styling and Configuration Difficulties and Inconsistent Documentation material-ui-pickers#1901. Example of UI we could output

Also cover how to change the header https://github.com/mui-org/material-ui-pickers/issues/1805.

• Have the CSS API documented, for instance: https://material-ui.com/api/autocomplete/#css
• Fix the Algolia no matches. So far we have:

• Fix the warnings throw by the demos
• Add a simple time picker example with the Autocomplete, use this model: https://material-ui.com/components/autocomplete/#disabled-options.
• Content proofread by a native English speaker.
• https://github.com/mui-org/material-ui-pickers/issues/1329 stop mapping the callback with the hook directly

const [selectedDate, handleDateChange] = useState(new Date());
<DatePicker value={selectedDate} onChange={handleDateChange} />

• Improve the accessibility of the demos. I have noticed a bunch of errors, I didn't look closer

report from https://chrome.google.com/webstore/detail/wave-evaluation-tool/jbbplnpkjmmeebjpijfedlgcdilocofh.

• Split ## responsiveness into 3 demos to collect stats usage between desktop, mobile, and responsive. This will help better prioritize our time.
• Drop DateRangeDelimiter component, use Box instead.
• Enable generation of API pages

Some of my notes to not forget:

• Fix ts typings for https://github.com/mui-org/material-ui/blob/master/test/utils/createClientRender.js

Closing as we mostly have standalone issues for each point now.
