<single-choice-dropdown label="Country of residence" bind="visible" placeholder="Please select a country" />
Using this underlines the placeholder as an attribute that doesn’t exist, and the placeholder also doesn’t appear when rendered, just the default “No value selected”
@cjmeyer Is your app on runtime version 4.84.0 (currently in RC)? Note that the placeholder attribute was only introduced in v4.84.0 of the runtime.
In regards to the underlined attribute in OXIDE: This is a result of this new attribute currently only being in an RC runtime version. It will show as valid in OXIDE once 4.84.0 is released to stable.
