I have a wide RadComboBox with Width set to 100%. When re-sizing the browser's window (IE, Chrome, FF) at some point the button is separated from the combo box. Image attached. Telerik version is 2015.1.401.45

Hi,

The observed behavior is a limitation of the Classic RenderMode of RadComboBox, which uses sprite images. I would recommend you to set the control's RenderMode property to Lightweight and take advantage of the HTML5/CSS3 rendering, which does not have such a limitation:

<telerik:RadComboBox ID="RadComboBox1" RenderMode="Lightweight" runat="server" Width="100%">
    <Items>
        <telerik:RadComboBoxItem Text="1" />
        <telerik:RadComboBoxItem Text="2" />
    </Items>
</telerik:RadComboBox>

I see only two options for RenderingMode: Simple and Full. However when I set it to Simple it rendered the combo the right way. And I see from the page source it uses standard SELECT in that case. Thank you!

My mistake. I used RenderingMode while had to use RenderMode. 

Setting RenderMode to Lightweight seems to be resolved the issue even when I use item templates.
