How do I reorder/rearrange parent pages on InDesign?

A bit late to the party I know, but the easiest method I've found is deselecting the Show Vertically for Parent Pages in the Panel Options window. In the same panel as suggested above, but you don't need to alter the page size. It seems much easier to move the pages around.

Hope this helps someone. Such a small thing, but so frustrating for us that need to move the parent pages!

If all else fails or if there are many parent pages to sort, you can use this script:

Same problem here (macOS 14.5, InDesign 19.5)

None of the suggestions, including Jumbo-ing the parent page icons or dragging by the name, seem to work.

As soon as you start dragging, the "apply parent" icon appears and no drop lines are ever shown.

Hi there, having read lots of solutions of how to do this, everyone misses out a key point. To move the parent pages you need to select the hamburger in the top right of the box and place a tick by 'Allow Document Pages to Shuffle'. Then when you grab the parent page to move it up or down it will give you a horizontal line between the pages where you can drop it to move it. Hope this helps everyone!

YOu can do it — its just very fiddly

<div style="padding:71.77% 0 0 0;position:relative;"><iframe src="https://player.vimeo.com/video/927930121?h=c9fd30c75c&amp;badge=0&amp;autopause=0&amp;player_id=0&amp;app_id=58479" frameborder="0" allow="autoplay; fullscreen; picture-in-picture; clipboard-write" style="position:absolute;top:0;left:0;width:100%;height:100%;" title="Screen Recording 2024-03-27 at 11.23.40"></iframe></div><script src="https://player.vimeo.com/api/player.js"></script>

What a UX failure. Everybody would understand it if there were a small line between the pages.

I figured out an easy way. Right click from the "pages" panel to open settings > Panel Options... > Parents = size = jumbo. Then it's much easier to drag to reorder the pages. Just click, drag, then release your mouse when your cursor is right in between the pages where you want it to be. Make sure you release in the grey space, and not over top of another page or you'll apply the parent to that page. When the thumbnail size is set to "jumbo" you have way more room between pages to drop and reorder. Hope this helps! 

Ugh. I didn't seem to have this problem until recently. I thought it was me; why would Adobe make it impossible to move Parent pages? I can't foresee every single page I need to create, and I frequently create new and rearrange the parent pages. Not being able to do so, when we could before, is infuriating.

This is infuriating.
Reordering parent pages is nothing unusual, nor should it be impossible - which, in my case, it seems to be.
