You can use the Id property to reference the DxDropDown control from the element that triggers the drop-down window. Set the trigger element’s aria-describedby attribute to the Id property value to allow a screan reader to read window content when the trigger element is focused.
<div id="dropdown-overview-target-container">
<DxButton aria-describedby="dropDown" Click="() => IsOpen = !IsOpen">
SHOW A DROPDOWN
</DxButton>
</div>
<DxDropDown
Id="dropDown"
@bind-IsOpen="@IsOpen"
HeaderVisible="true"
HeaderText="Header"
BodyText="@Constants.Content"
Width="max(25vw, 250px)"
PositionTarget="#dropdown-overview-target-container" />
@code {
bool IsOpen { get; set; } = false;
}
