featurelayer label with subscription or supscription

[Lazyman]

Hi，I want to add labelingInfo for a featurelayer, and the label is combine with two field values, like Field1_Field2，or Field1<sup>Field2</sub>. I don't know how to set the labelExpressionInfo, as it seems no sub or sup support for arcade expression or html tag.  

Looking forwading to you help, thank you!

Hi @Lazyman, thanks for posting your question here. Currently, we don't have labeling support for subscript and superscript. As an alternative, this sample shows some formatting options with multiple label classes: https://developers.arcgis.com/javascript/latest/sample-code/sandbox/?sample=labels-multiple-classes
