    Hello, the bug is very easy to reproduce. This is the 4th bug I've found with decorator in one month after start using it with Lightmode rendermode, evidently it is flimsy and needs testing.

    Hello Aarsh,

    In Q1 2014 we have made some improvements to the responsive capabilities of the RadFormDecorator (see this help article) which leads to the mentioned issue. I have logged the issue in our feedback portal here, so that you can monitor its progress, put your comments below and vote. For the time being you can use the following CSS workaround:
        .rfdSelect.rfdSelect_Default {
            min-height: 1.417em;

    As a small token of gratitude for reporting this issue to us I have updated your Telerik points.
