Hi everyone!
I’m thrilled to announce that we are rolling out Multi-select custom fields in Asana! 
Multi-select custom fields allow the selection of several values at a time. For example, a Social Media Manager needs to assign different channels to the assets they keep track. This and more use cases will be now possible using multi-select custom fields!
Going forward, you will be able to select “Multi-select” in the Field type when creating new custom fields.
Please note we are gradually rolling out this feature and we hope to implement it to all customers by end of October. If you don’t have access yet, it will be available soon. Thanks for your patience and if you have any feedback or questions please create new requests in the #productfeedback and #tipsandtricks categories! We will be happy to help!
