Description

A dropdown widget that displays a list of string options for the user to select one. Backed by an FString array with full Blueprint support for dynamic option management.

Caveats & Gotchas

• Options added via AddOption() at runtime are not reflected in an open dropdown until RefreshOptions() is called.
• The Font and ForegroundColor properties can only be set before the widget is constructed (via Init functions in the constructor) — changing them at runtime has no effect.
• OnGenerateWidgetEvent lets you customize each item row; if unbound, a default STextBlock is created using the Font property.

Example

Populate dropdown at runtime C++

MyComboBox->ClearOptions();
for (const FString& Option : AvailableOptions)
{
    MyComboBox->AddOption(Option);
}
MyComboBox->SetSelectedOption(AvailableOptions[0]);
