Release 3.0.0
Created on: 15 Jun 2021 17:11
Category: DropDownList
Type: Bug Report
Dropdown closes immediately after opening on mobile device



This behavior is observed in the DropDownList when filtering is enabled and in the ComboBox regardless of whether filtering is enabled or not.

The (filter) input gets focus, which shows the soft keyboard, which changes the viewport size, which causes the dropdown to hide. Unfortunately, there is no workaround at the moment (except perhaps disabling filtering for small viewports).

Hi Ivan,

The bug was fixed prior to the release, so this is why its status appeared completed a couple days earlier than the release date. The fix actually became available with version 3.0.0 of Telerik UI for Blazor which was released on January 19th. Having this in mind, if you now upgrade to 3.0.0 you should not experience the bug.
