Hi Rudolf,

The Placeholder parameter directly translates to the placeholder HTML attribute and as such it cannot have icons, it can only take a plain text string.

If you can add your custom icon to the placeholder of a plain <input type="text">, the same CSS would likely work for the Telerik inputs as well.

That said, I must mark this as declined as it is not a typical feature of HTML and even if there is a CSS way for it, it is quite hack-ish.

On a side note - the dropdownlist component does not have a placeholder at all as <select> elements never do, it has an empty text setting that is still plain text. It does, however, have a ValueTemplate where you can render your own content.
