`List`¶

Render ordered or unordered items from child values.


Import	`from hedron import List`
Distribution	`hedron`
Backend activity	No
Normal render mode	`RenderMode.FRAGMENT`

The preview is a local docs simulation (not a running Hedron server). Interactive demos show a “Simulated HTMX” trace when applicable.

Basic use¶

from hedron import List

component = List('Create a branch', 'Add the component', 'Run checks', ordered=True)

Compose under Page for full documents, or return from a fragment route for HTMX swaps.

How it works¶

Each supplied item becomes one native li inside ul or ol. Nested structure should be built explicitly so list hierarchy remains inspectable.

This component's core behavior is server-rendered HTML and does not require a browser runtime. The preview is ordinary semantic HTML, so keyboard, form, link, and disclosure behavior comes from the platform.

Constructor and parameters¶

List(*items, ordered=False)

Parameter	Type	Meaning
`items`	`NodeLike`	Values wrapped in list items.
`ordered`	`bool`	Use `<ol>` when sequence matters.

Composition and backend behavior¶

Keep List at the smallest semantic boundary. Fragment routes should return only the replaced region and preserve stable target IDs across success, validation, empty, loading, and error responses.

This component is primarily presentational; keep any mutation on an explicit action or component route.

Accessibility¶

Choose ordered lists only when changing the sequence changes the meaning.

Security¶

Escaping and SafeUrl / TrustedHtml are framework concerns; authorization and data exposure remain application code. Redact secrets before rendering.

Common mistakes¶

Do not type bullet characters into Text; use List so assistive technology receives list semantics.
Do not copy docs-preview JavaScript into an application server.

Testing¶

from hedron import RenderMode, render

result = render(component, mode=RenderMode.FRAGMENT)
assert result.html
assert not result.diagnostics
