Hi Tracey,

I hope you are doing well!

I understand that you're encountering issues with the positioning of RadEditor dropdowns on your webpage. The symptoms of the problem you're facing look similar to what's described in the article Incorrect Positioning of Controls. To tackle this, I recommend thoroughly inspecting the page's stylesheet. Look for global and inline CSS rules that could be influencing the popup's positioning. Key properties to check include position: absolute, position: fixed, position: relative, margin: auto, top, and left.

If you're unable to identify such styles, or if the solutions suggested in the article don't resolve the issue, I'd like to ask you to provide a stripped-down version of your project (aspx, aspx.vb, CSS, masterpage) that demonstrates the problem. I will examine and debug it and do my best to provide a solution.

Additionally, could you please:

• check if this issue is replicable in the live demos of RadEditor as well as test by setting the RadEditor's RenderMode property to "Lightweight"? This could provide further clues as to whether the problem is specific to your environment or a broader issue.
• Test with the latest 2024 Q1 version of the controls.

Thank you for your cooperation, and I look forward to assisting you further in resolving this matter.

Best Regards,
Rumen
