Bootstrap 5 akordion menjadi terlalu lebar apabila dikembangkan

Question

Saya menjangkakan komponen akordion akan mengembang agar sepadan dengan lebar elemen induknya, tetapi apabila ia mengembang, ia bukan sahaja mengembang sendiri, tetapi juga elemen induk, menyebabkan anak tetingkap kiri menjadi mampat dengan banyak. Apakah yang perlu dilakukan untuk mencapai tingkah laku yang diingini? Saya akan menghargai sebarang jawapan.

Saya cuba melaraskan sedikit lebar tajuk akordion dan kandungannya, tetapi itu tidak berjaya.

Answer 1

#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 kategori). Walau bagaimanapun, apabila kandungan akordion dipaparkan, kandungan tersebut akan cuba mengambil sebanyak mungkin ruang mendatar.

Untuk mengelakkan perkara ini, sila pertimbangkan #pane kanan元素上设置某种flex-basis或width，例如width ：25%通过w-25` di sini:
