付録でページ区切りを避ける

Question

見出しを同じページに表示しようとしており、 と の使用もすでに試しましたが/nopagebreak、samepageそれでもページが分割されます。私の理解では、PDF のサイズは、見出しが 1 ページに表示できるほど小さくする必要があります。

そうあるべきだ

Anhang
A Gesetzesauszüge
A.1 Gesetzesauszug Zivilrecht: Art. 3, Abs. 1
Sōzoku no kōryoku. Sōsoku [Auswirkungen der Vererbung. Vererbung] (1947): Art. 3, Abs. 1.
