Bootstrap 4 - Modale
Descrizione
Modal è una finestra figlia che è sovrapposta alla sua finestra genitore. Visualizza il contenuto da una fonte separata che può avere qualche interazione senza lasciare la finestra principale.
Modale di base
Crea un modal utilizzando la classe .modal e l'attributo data-toggle = "modal" su un elemento, come un pulsante o un link, insieme a un data-target = "#identifier" o href = "#identifier" per scegliere come target uno specifico modale per alternare.
Un esempio di finestra modale statica è mostrato nel seguente esempio:

Centrato verticalmente, utilizzando la griglia, i suggerimenti e i popover
È possibile effettuare la modal verticale centrale con l'aggiunta di .modal-dialogo centrato classe per .modal-finestra elemento. Usa il sistema a griglia all'interno di una classe modale aggiungendo .container-fluid class all'interno della classe .modal-body . Puoi posizionare i suggerimenti e i popover aggiungendo gli attributi data-toggle = "popover" e data-toggle = "tooltip" .
Il seguente esempio dimostra l'utilizzo dei modi sopra indicati:

Contenuto modale variabile
Puoi avere un gruppo di pulsanti per avviare modali con contenuti diversi. Utilizzare la proprietà event.relatedTarget (restituisce la destinazione correlata di un elemento) e gli attributi HTML data- * per visualizzare il contenuto a seconda del pulsante su cui si è fatto clic.
Il seguente esempio lo dimostra:
