Header
Documentazione ed esempi per la creazione di una testata di navigazione.
L’header di un sito della Pubblica Amministrazione è solitamente composto di 3 elementi principali:
- Un cosiddetto Slim Header, una sottile fascia dello stesso colore o, preferibilmente, di colore lievemente più scuro rispetto al tema principale del sito, che mostra alcuni link funzionali con impatto globale o esterno al sito stesso.
- Un Header Centrale che identifica in modo chiaro il sito attraverso logo, testo e social, e può contenere un link per effettuare ricerche sul sito.
- Un Header Nav dedicato alla navigazione, visibile su schermi di grandi dimensioni ed accessibile attraverso il classico pulsante di tipo “burger menu” () per dispositivi mobili.
Accessibilità
Condierando l’importanza dell’Header per la navigazione di un sito, si consiglia di seguire attentamente gli esempi per quanto riguarda l’utilizzo di attributi ARIA e labelling accessibile.
Il titolo del sito, “Nome dell’Istituzione” negli esempi, è contenuto in un <div> generico e non un tag <h1> per evitare conflitti con gli <h1> presenti nelle singole pagine. Nel caso in cui la home page fosse priva di un titolo relativo all’Istituzione (es: carousel con ultime notizie) è consigliabile applicare il tag <h1> al titolo dell’header unicamente in quella pagina.
Maggiori dettagli sull’accessibilità del megamenu sono presenti nella relativa pagina.
Slim Header
Lo Slim Header mostra un’intestazione, solitamente con riferimento all’ente di appartenenza del progetto o riferimenti utili, oltre ad un eventuale menu per il cambio lingua e l’accesso ad area riservata.
Il cambio lingua è gestito con il componente dropdown.

</header>Header Sticky
Affinché la testata rimanga visibile in formato ridotto anche allo scorrere della pagina, è sufficiente utilizzare la classe .it-header-sticky nell’elemento identificato con la classe .it-header-wrapper.
<div class="it-header-wrapper it-header-sticky">...</div>
È disponibile una pagina di esempio dedicata a questa funzionalità per comprenderne appieno significato ed utilizzo.
Tramite JavaScript
E’ possibile inizializzare il componente tramite JavaScript:
var headerSticky = new bootstrap.HeaderSticky(document.getElementById('myHeaderSticky'), options)
Metodi
Metodi asincroni e transizioni
Tutti i metodi API sono asincroni e avviano una transizione. Ritornano al chiamante non appena viene avviata la transizione ma prima che termini. Inoltre, una chiamata al metodo su un componente in transizione verrà ignorata.
Per maggiori informazioni consulta la documentazione Javascript di Bootstrap (in inglese).
getOrCreateInstance
Metodo statico che consente di ottenere l’istanza di un HeaderSticky associata ad un elemento del DOM o di crearne una nuova nel caso non fosse stata inizializzata.
var headerStickyElement = document.querySelector('#myHeaderSticky')
var headerSticky = bootstrap.HeaderSticky.getOrCreateInstance(headerStickyElement) // Returns a Bootstrap modal instance
