Folder in layer list?

[muesliq]

Mapbox Studio supports folders via metadata properties, if I'm not mistaken. I am not proposing to do the same, as this is a proprietary approach.

Yet there's a non-proprietary possibility to do the same: We could automatically bundle all adjacent layers that start with the same word into a folder.

Look at this example:

This would look like this:

• background
• landcover-glacier
• landuse..
• park..
• landuse..
• landcover..
• waterway..
• water-offset

Less than half the length.

Very good idea for grouping by the prefix!!!!

I also have problems working with 100 layers style to still find my styles.
I would like that feature as well - not much time left to do all these cool features but we'll see.

The only implementation issue might be that it makes drag and drop harder.

Note to myself: I can probably reuse the collapse components to make this very straightforward.

By the way, this feature would incentivise proper layer naming :-)

Works now! It's quite a hack implementation wise because otherwise drag and drop get's broken.
But for using it is it works ok (hope it doesn't confuse users though).

Especially the group reordering can be confusing at first.
Because when you move a layer out of a prefix group or into it it will form a new group.
Still think we should keep it though.

Thanks for pushing me - wouldn't have implemented it otherwise but the trick with the prefix is very neat (and does not make us copycats - which is even more important to me).

OSM Liberty has 100 layers - and there it really helps organizing.

I would close folders by default, otherwise the benefit is limited.

It is now collapsed by default e5fbe3b
