How to show gallery inside of gallery

[TKShimmm]

Dear Travis,

Firstable, I fully appreciate for such a useful resource that you created.

However I'm having this little trouble showing galleries inside contents.

for example, I created React-tutorial, and React-tutorial has several chapters. In my notion page I created gallery so I can organize my contents. But on browsers, chapter gallery does not appear at all.

Right after I wrote this, I kind of solve the problem..
problem was database that I use was copied from other page.
if I create gallery inside content, database will belongs that contents and apears.

In this case, I got new trouble...

Trouble is... that gallery I create inside my contents, has only one single vertical line, and every contents has enormous size..

plz help me with this trouble

Thank you so much, and hope you all the best!! :):):)
