Hi  @Khiem Duy Tran

 , this is done! We're working to make this easier for users to do for custom pipelines like this. Stay tuned for future update on that.

thanks  @Woody Butler

 , but how can we delete pipeline? sorry i tried to find it but can't, thank you for your support ! 

To archive future pipelines, you can do so under the Stages -> settings page for the pipeline.

For most pipelines you can click "edit stages", then "settings" then "archive funnel"

However, we've realized that some of the custom type pipelines are missing this edit stages button, so we are working on adding that back in. To get around this, you can append a "/manage" to the pipeline url to get to the stages page for a pipeline.

thank you very much Woody ! will do it !
