Dropdown with Virtual Scroll and Groups #79
-
|
Does PrimeNG's Dropdown component support Virtual Scroll activated per group, and if so, how can this functionality be utilized? The documentation does not provide examples for this specific feature. In the version 13.x we used it per group and it works per group. In the latest version unfortunately it is not working anymore. |

Hi, To make it clear could you please explain As I understand from above, unfortunately, it's not supported per group but maybe you can assign the group's height as scrollHeight and it might work. In the new virtual scroll implementation, you need to define a We've reworked the virtualscroll in v14. Because of that, some features of v13 might not work as you expected in >= v14. |

Thanks for this information! Unfortunately, we also have considerable performance problems with the new version regarding this feature, which were not before. We will investigate. |
