Will be good addition

I'm still hung up on the inability to search/sort/filter on multiple labels.

Yes! Hierarchical display & management of labels, being able to expand & collapse them the same way as Proton does with folders.

Come on, please offer this feature. Or at the very least, please be transparent and explain why you're not implementing this very widely requested feature. You already know that many people, who really want to switch to ProtonMail from Google, are still sticking with Gmail because Proton still, after all these years, does not offer nested labels. You guys pride yourself on transparency, right? Well, here's your chance to prove that — why is this feature not yet implemented? Does it have to do with technical limitations? Is it not a priority despite how widely requested this feature is? What is it?? Please, just address this issue!

Since apparently folders and labels share a namespace, it would be useful to be able to put labels into folders. I've just imported *two* Google accounts, each of which is over a decade old, and a single unsortable list is not helpful.

This doesn't make sense to me. We have nested folders now and I'm not sure how or why you'd nest a label as a label is not a location so there's nothing to nest into.

Nested labels are essential for me. It's the one missing feature preventing me from switching to protonmail completely.

Allow folders and their respective sub-folders to be collapsed. Would allow for a cleaner side tab when the user has many folders with subfolders. Similiar to what gmail offers. Apply this to labels as well.

My Gmail migration just crashed because your system didn't understand my nested labeling :(

Allow creation of sub-labels and parent labels just as is available for folders

Please implement nested labels. I want to ditch gmail but I can't without this. I don't want a list of a zillion different labels. I have major labels like work, kids, travel, and under them I have sub-labels for many different things.

I tried folders, but folders don't solve the problem of this huge long list of labels, where in gmail I have just a short list of main labels that I can expand to see all the sub-labels.

This is what will keep me from using protonmail as my main email and I will search for another non-google solution. Perhaps the rumored X-mail if it's any good.

there's not even a need to implement 'nested' labels specifically, IMO the idea of nesting labels is an implementation choice by Google that didn't fully get or maximize the power of labels.

Simply allow searching by more than one label, which achieves the same result more elegantly. There's no need for nested `reservations/air` label when we can just apply `reservations` and `air` and search for BOTH of them together.

Please implement nested labels, it's one of the main things preventing me from finishing migrating fully from Gmail.

Sorry if duplicated...I've not used labels yet, but if you have assigned labels then one thing is necessary; the ability to reassign existing labels for all email messages to another label. Especially if nested labels are implemented.

This is definitely a big feature to be missing! The current folder / label paradigm works for some people, but I have only ever been comfortable with nested labels for sorting messages.

Please consider adding this useful feature.

Still no traction on this? I don't understand why they use both folders and labels. Apart from being far superior in function, labels can be used as a full replacement to folders with no drawbacks at all. The only benefit folders offer is that it can have sub-folders, but that is only because Protonmail hasn't implemented nested labels.

This is the singe reason why I keep my Google business account. I have been waiting several years for this to be implemented. Please remove the folders and go all in on labels.

This ticket dates back to 2015! What a shame.

Nested labels are incredibly convenient and are supported by my former email provider (fastmail - see https://www.fastmail.help/hc/en-us/articles/360058753554-Setting-up-and-using-labels). Importing seems to put things into nested folders instead and it isn't clear how multiple labels on a single message are handled.

Also, there appears to be a nesting limit on folders within proton mail (3 deep?) that it would be nice to have removed.

@Adriano Can I put an email inside 2 differents nested folders?

Because I could put 2 differents labels on a folder.

You can use nested folders instead.
