L'accordéon Bootstrap 5 devient trop large lorsqu'il est étendu

Question

Je m'attendais à ce que le composant accordéon s'agrandisse pour correspondre à la largeur de son élément parent, mais lorsqu'il se développe, il se dilate non seulement lui-même, mais également l'élément parent, ce qui entraîne une forte compression du volet de gauche. Que faut-il faire pour obtenir le comportement souhaité ? J'apprécierais toutes les réponses.

J'ai essayé d'ajuster légèrement la largeur du titre en accordéon et son contenu, mais cela n'a pas fonctionné.

#right-pane 元素没有显式声明 flex-basis 或 width，因此它将占用所需的空间。当手风琴关闭时，它会按照您的预期工作，因为它的内容宽度较窄（然后由于 flex-grow 中的 flex-grow: 1 ，然后会增长以填充剩余空间-1 catégorie). Cependant, lorsque le contenu de l'accordéon est affiché, celui-ci tentera d'occuper autant d'espace horizontal que possible.

Pour éviter cela, veuillez considérer #right-pane元素上设置某种flex-basis或width，例如width ：25%通过w-25` ici :
