`Label`¶

Associate visible text with a form control ID.


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

Live demo¶

Search projects

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 Label

component = Label('Search projects', for_='project-search')

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

How it works¶

for_ uses the Python-safe spelling but serializes to the native for attribute. Prefer FormField when you also need help, required, or error binding.

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¶

Label(text, *, for_=None)

Parameter	Type	Meaning
`text`	`str`	Visible label.
`for_`	`str \| None`	Target control ID; renders as `for`.

Composition and backend behavior¶

Keep Label 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¶

Labels should state what information to enter, not merely repeat a placeholder.

Security¶

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

Common mistakes¶

A placeholder is not a replacement for Label because it disappears during entry.
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
