Framework7 - Akkordeon
Beschreibung
Das Akkordeon ist ein grafisches Steuerelement, das als gestapelte Liste von Elementen angezeigt wird. Jedes Akkordeon kann erweitert oder gedehnt werden , um den mit diesem Akkordeon verbundenen Inhalt anzuzeigen.
Zusammenklappbares Layout
Wenn Sie ein einzelnes, zusammenklappbares Element verwenden, müssen Sie das Wrapper-Element für die Akkordeonliste weglassen .
Es folgt eine Struktur des zusammenklappbaren Layouts -
<!-- Single collapsible element ------>
<div class = "accordion-item">
<div class = "accordion-item-toggle"></div>
<div class = "accordion-item-content"></div>
</div>
<!-- Separate collapsible element -->
<div class = "accordion-item">
<div class = "accordion-item-toggle"></div>
<div class = "accordion-item-content"></div>
</div>Die folgenden Klassen werden in Framework7 für Akkordeon verwendet -
| S.No. | Klassen & Beschreibung |
|---|---|
| 1 | accordion-list Es ist eine optionale Klasse, die eine Gruppe von Akkordeonelementen enthält. |
| 2 | accordion-item Es ist eine erforderliche Klasse für einzelne Akkordeongegenstände. |
| 3 | accordion-item-toggle Es ist eine erforderliche Klasse, die zum Erweitern des Inhalts von Akkordeonelementen verwendet wird. |
| 4 | accordion-item-content Es ist eine erforderliche Klasse, die für den Inhalt versteckter Akkordeongegenstände verwendet wird. |
| 5 | accordion-item-expanded Es ist ein einzelnes erweitertes Akkordeonelement. |
