How do I filter to exclude a label? (Trello)

[1]

I would like to filter my cards in a board to show everything that doesn't have a certain label. How do? I've tried -label:"red" and -label:"Urgent" and that syntax doesn't work.

[Torben_trello]

It's not possible to add a negative operator to filters, but the search feature does support that: http://help.trello.com/article/808-searching-for-cards-all-boards

[Mickie Shipley]

Is this a possible feature for the future? 

[Gabe Castillo]

We would like this feature as well.

[Rostislav Simonik]

Would be great to has given feature, maybe filter by search query to reuse given logic. 

[Jennifer Greco]

I would like this as well - search for all cards that do not include one label. Seems like it would be a big help to many.

> but the search feature does support that

Yeah, that would be why the question specified filter ;-)

[Martin Buresch]

I really appreciate to have such a Feature to exclude labels in the filter option

[Peter Woodman]

This is a feature I would use a lot as well.

[spencerwasden]

I would like to see this working in the filter as well.

[Tom_Brown]

I'd like to do this so I can find all cards not done

[cassandra]

Yes that would be exactly  how I would use it as well. Show any card is is not marked Done for example.

This feature would be very helpful

[Christophe Broult]

That would be quite useful indeed.

[Karena Kreger]

I also would need this!

[José Vieira]

upvote on that! :) filter out labels would be a great feature ;-)

[Fivetee]

Needs this too. Hope that helps ;)

[fiona dower]

We need this too. Has it been implemented yet?

[Nathan Cayzer]

Such an important feature... PLEASE add!

[Marc Pfeiffer]

Would love to have this as a feature too please

[tallcoder]

100% need this feature. I'm kinda shocked it's not a thing yet.

Logged in for first time to upvote. 

[Biel]

indeed an important, and I'd expect widely used, feature

[ben]

Me too please. This would be very helpful. 

[Ryan Walsh]

The search workaround suggested here isn't as useful as being able to see my normal view of the whole board but with certain cards excluded based on which labels they have. I'd really appreciate that view. Thanks.

[Johannes Pöhlmann]

I agree. The search workaround is not very helpful. The search list disappears when I click on one item. The filter keeps in place once I open and close a card. This is what I need. 

[kenneth-loh]

It is unfathomable that anyone could have left out this feature at the first place, let alone leaving it out for another 4 more year!

[biofsoares]

I so would like to have this feature too. My most used board has 26 labels. Searching and filtering NEED exclusions.

@Mickie Shipley 
Any update on this, please?

[Gabe Castillo]

It's almost been 4 years since this issue was raised. Is this on the roadmap? It is difficult to create our workflows without label exclusion.

[Johannes Pöhlmann]

It‘s a must have feature for me. Sorting by filter keeps the cards in its lists. And it works within the app.

[Mutahhar]

I am in need of this feature too...

[Erhan Arat]

Add this feature please!!!

Here's how I was able to do this using the browser's developer console:

Quick answer:

To hide all the cards with the stock pink label:

x = Array.from(document.querySelectorAll("a.list-card:has([data-color=pink])"));

x.forEach(x => {x.style.display="none"});

Full procedure & details:

1. While on the board, scroll so that the label you want to filter against is visible on a card.
2. Open developer tools via F12, Ctrl+Shift+i, or the menu.
3. Click 'Inspect' or Ctrl+Shift+c, then mouse over the label itself (not the whole card)
4. Look at the HTML of the selected element, and the child elements - there should be a button element or similar with some fairly distinctive aria attributes, and if it's one of the stock labels, "data-color". Note one of these attributes. In my example, I note that the stock pink label (the one with hotkey 9).
5. Go to the Console tab of developer tools, or show the console below the Elements view.
6. Input the code in the block above.

Explanation of the querySelectorAll parameter:

":has()" is a "relational pseudo-class" CSS selector - see https://drafts.csswg.org/selectors/#relational .

Cards in Trello are <a> elements, and they (usually? all?) have a CSS class= attribute including the class "list-card".

The visible label tags on cards are somewhere within the HTML of the card's <a> element.

So, this selector says, "give me all <a> elements that are cards, and which also have some sub-element with an attribute named data-color that has the value pink." Or, looking at it another way, "look at all the elements with the attribute data-color=pink, go up through the ancestors of each of them, then return any that happen to be cards".

[Matthew Beadlecomb]

This is a very simple work around for the time being. Thanks for posting!

I have found a bit of a workaround which will give you a list of cards that DO NOT have certain labels.

Its using the trello Dashcards powerup to count the cards that meet the "not that label" criteria. and in doing so provides a list of all the cards that comply, which you can export to CSV for further examination.

Its not a replacement for being able to filter the cards in place within the board, but at least gets you the card data you are looking for.

[Lisa Roberts]

Thank you, unfortunately not allowed for my board.  Since it does not fully meet requested functionality I will not pursue requesting company to allow.
