How do I custom sort photos in Lightroom Ver 8.2?

Hey, @RST1851. Welcome to the Adobe Community! 😊 I'll help you get started with Sorting and filtering in Lightroom. 

Custom ordering is unavailable in All Photos, but you can find this option when importing albums into the Grids (Photo grid & Square Grid you make in Lightroom. 

Here is how it works: 

1 - Grid View: Ensure you're in the Grid view by pressing G.

2 - At the bottom toolbar, find the sort options.

3 - Select Custom Order to Drag and Drop: Click and drag your photos to arrange them in your desired order. You'll see a highlighted space where the photo will be placed.

4 - Lightroom will automatically save this custom order for you.
