bugfix: add HTMLAttributes Prop Type

[happy-devs]

Some components like Panel are showing errors when attributes like children are supplied. I'd suggest providing the HTMLAttributes<HTMLDivElement> type alongside the basic StandardProps; I'm happy to look through which ones need updating as a contributor.

NotGovUK/components/panel/src/Panel.tsx

Lines 6 to 9 in ff61068

	export type PanelProps = StandardProps & {
	/** Heading of the panel */
	title: string
	};

ERROR:
Type '{ children: (string | Element)[]; classModifiers: string; title: string; }' is not assignable to type 'IntrinsicAttributes & StandardProps & { title: string; }'.

@happy-devs: Sorry I missed this. I think this appears in newer versions of React. (What version are you on?)

Obviously, we will need to update the code to explicitly declare when children are valid. I'm not yet certain of the best approach for doing that across the board.

In the case of the Panel component, I agree we should allow all of the <div> attributes and so use HTMLAttributes<HTMLDivElement>.

Feel free to raise a PR, or I'll add it to my to-do list.

Thanks for raising this.
