## Context

During a BAU I was requested to include custom section IDs, in the case of divided and basic sections, I haven't found a way to do so on the title of the section.

My code snippet:

```python

{{ vf_divided_section(
title={"text": "NVIDIA DRIVE"},
blocks=[
{
"type": "description-block",
"items": [
{
"type": "logo-block",
"item": {
"logos": [
{
"attrs": image(
url="https://assets.ubuntu.com/v1/1f419e4d-accelerated_by_nvidia.png",
alt="NVIDIA DRIVE",
width="378",
height="312",
hi_def=True,
loading="lazy",
attrs={"class": "p-image-container__image"},
output_mode="attrs"
)
}
]
}
},
{
"type": "description",
"item": {
"type": "html",
"content": (
'

Ubuntu is the open source software foundation for NVIDIA DRIVE®.

'
'

Canonical provides the production-grade Linux for NVIDIA DRIVE platforms. Ubuntu delivers a secure, maintained and widely adopted software environment that enables software-defined vehicle developers to deploy immersive experiences and autonomous driving applications at scale.

)
}
}
]
},
{
"type": "divided-block",
"bullet_type": "none",
"items": [
{
"contents": [
{
"type": "cta-block",
"padding": "shallow",
"item": {
"link": {
"content_html": "Get in touch to learn more about Ubuntu and NVIDIA DRIVE ›",
"attrs": {
"href": "/contact-us",
"class": "js-invoke-modal",
"aria-controls": "contact-modal"
}
}
}
},
{
"type": "cta-block",
"padding": "shallow",
"item": {
"link": {
"content_html": "Explore Canonical’s automotive solutions ›",
"attrs": {
"href": "https://canonical.com/solutions/automotive"
}
}
}
}
]
}
]
}
]
) }}
```

### Possible solutions

1. Accept argument `attrs`:
```diff
title={"text": "NVIDIA DRIVE"},
+ attrs={"id": "nvidia-drive"},
```
2. Allow for HTML title:
```diff
- title={"text": "NVIDIA DRIVE"},
+ title_html="

NVIDIA DRIVE

"
```

Start by locating the Basic and Divided section component implementations and how their title argument is rendered. Confirm the chosen API supports a custom section ID without breaking existing titles, and verify the rendered heading or section output for both variants.
