Layout

AppForm

A page-level form layout with a fixed header, a scrollable body and a sticky footer.

<script>
  import { AppForm, FormSection, TextField, Button } from "@codeatlasdev/ui";
</script>

<AppForm title="New user" backHref="/users">
  <FormSection title="Account">
    <TextField label="Name" bind:value={name} />
  </FormSection>
  {#snippet footer()}
    <Button variant="ghost" href="/users">Cancel</Button>
    <Button variant="filled" onclick={save}>Save</Button>
  {/snippet}
</AppForm>

AppForm fills its parent, so give the parent a height. It replaces the removed FormPage. For a floating action bar inside your own scroll container, use StickyActions.
