#Passing components for HTML elements in MDX content collections

Hi @fallen timber. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
Based on the knowledge sources, you can pass custom components to MDX content via the components prop when rendering imported MDX content. This works for many standard HTML elements, such as blockquote or h1, by mapping them to your custom components in the components object:
<Content components={{ ...components, h1: Heading }} />
or
export const components = { blockquote: Blockquote }
in your MDX file, and then use the components prop when rendering <Content /> in your Astro component. This approach is documented for elements like blockquote, h1, etc. [Using Components in MDX]
However, the knowledge sources do not explicitly confirm that the details element is supported for this kind of component replacement in MDX. The official documentation provides examples for elements like blockquote and headings, but does not mention details as a supported target for custom component mapping [Using Components in MDX].
Therefore, if your <details> elements are not being replaced by your DetailsComponent, it is likely because MDX does not support overriding the details element in this way, or it is not included in the list of elements that can be mapped to custom components.
