How do you define an element with an ID attribute using LWC?
I'd like to be able to link to certain portions of my page using URL fragments, eg:
<h3 id="overview">Overview</h3>
...
<a href="#overview">Go to Overview</a>
Unfortunately the IDs i set from within LWC templates get overwritten, so my links don't work. Is there any way to define the ID attribute so it won't change?

Yes, you can use data-id and the HTMLElement dataset property.
<h3 data-id="overview">Overview</h3>
const element = this.template.querySelector('[data-id="overview"]');
// element.dataset.id === 'overview'

Assuming you want to scroll to an element you have access to, you could always use scrollIntoView:
this.template.querySelector("h3").scrollIntoView();
You can basically use any valid CSS selector to find a specific element (e.g. based on a data-id or another attribute).
As far as I can tell, from a lack of documentation, you can't specify an anchor target. You would write the link like this:
<a onclick={handleClick} data-target-id="overview">Overview</a>
Given an H3 like this:
<h3 data-id="overview">Overview</h3>
And scroll with this:
handleClick(event) {
let targetId = event.target.dataset.targetId;
let target = this.template.querySelector(`[data-id="${targetId}"]`);
target.scrollIntoView();
}
((Note: Not tested, you might need to tweak the CSS selector.))
This assumes that the link and target are in the same template, otherwise this won't work. As far as I can tell, you can't target arbitrary elements.
