Text fields export types dropdown with different export options. This allows you to select the type of output for text fields.
Currently text is exported with div tag and span tag.
<div> <span>Text here</span> </div>
But there are times when you want to use paragraph, span only or no tags at all.
<div> Text here </div>
<p> <span>Text here</span> </p>
If this option was set on the artboard all text fields would export this way.
