#Collapse

Hmm, I don't know enough to give you a confident answer yet. The code you've provided seems to be using a Collapse component, which is not directly related to Astro. It's also using a map function to iterate over documentsSections and documentsTypes, and it seems to be filtering and displaying some documentsFiles.
However, without more context or a specific error message, it's hard to provide a solution. If you're encountering a specific issue, could you please provide more details? What exactly is the problem? Are there any error messages?
If you're working with Astro, you might find the Astro Troubleshooting Guide (https://docs.astro.build/en/guides/troubleshooting/) helpful. It provides guidance on creating minimal reproductions of your issue, which can be very useful when asking for help or reporting bugs.
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

@peak jacinth show me example of using map in map

Let me check the knowledge base for you. One moment! :books:
Sure, here's an example of using a map function inside another map function. This is often done when you have nested arrays or objects. In this case, you're iterating over an outer array with the first map, and then over an inner array with the second map.
This example is taken from the Astro documentation on sharing state between islands (https://docs.astro.build/en/recipes/sharing-state-islands/#using-maps):
return $isCartOpen ? (
<aside>
{Object.values($cartItems).length ? (
<ul>
{Object.values($cartItems).map(cartItem => (
<li>
<img src={cartItem.imageSrc} alt={cartItem.name} />
<h3>{cartItem.name}</h3>
<p>Quantity: {cartItem.quantity}</p>
</li>
))}
</ul>
) : <p>Your cart is empty!</p>}
</aside>
) : null;
In this example, Object.values($cartItems) returns an array of cart items. The outer map function iterates over this array. For each cart item, it creates a list item (<li>) with an image, a heading, and a paragraph. The image source, heading text, and paragraph text are all taken from the properties of the current cart item.
This is a common pattern when you want to create a list of elements based on an array of data. The map function is perfect for this because it creates a new array by applying a function to each element of an existing array.

Sure, here's another example of using a map function inside another map function. This example is taken from the Astro documentation on querying your database (https://docs.astro.build/en/guides/astro-db/#relationships):
<h2>Comments</h2>
{
comments.map(({ Author, Comment }) => (
<article>
<p>Author: {Author.name}</p>
<p>{Comment.body}</p>
</article>
))
}
In this example, comments is an array of objects, where each object contains an Author and a Comment. The outer map function iterates over this array. For each comment, it creates an article (<article>) with two paragraphs (<p>). The text of the first paragraph is the name of the author of the current comment, and the text of the second paragraph is the body of the current comment.
This is a common pattern when you want to create a list of elements based on an array of data. The map function is perfect for this because it creates a new array by applying a function to each element of an existing array.

<h2>Comments</h2>
{
comments.map(({ Author, Comment }) => (
<article>
<p>Author: {Author.name}</p>
<p>{Comment.body}</p>
</article>
))
}
add comment.map

Let me check the knowledge base for you. One moment! :books:
Sure, if you want to map over another array inside the comments.map(), you would need to have a nested array. Let's assume each Comment object has a replies array that you want to display. Here's how you could do it:
<h2>Comments</h2>
{
comments.map(({ Author, Comment }) => (
<article>
<p>Author: {Author.name}</p>
<p>{Comment.body}</p>
<ul>
{Comment.replies.map((reply) => (
<li>{reply}</li>
))}
</ul>
</article>
))
}
