This add-on currently depends on ember-basic-dropdown (EBD) v3, which uses the {{with}} helper which is deprecated (and raises a build-time warning) in Ember v3.26+ and removed in Ember v4.0.

Currently working in an app (which we are slowly working towards upgrading to Ember v4) that directly depends on EBD v6 for other reasons and this package doesn't seem to conflict with it (apart from still raising the warning). Would be willing to submit a PR to update to ember-basic-dropdown v6 (which supports Ember v3.28+), or alternatively allow this package to accept a range of acceptable versions of EBD.
