Hi tamir.we

WebViewer doesn’t support labels for text form field widgets and signature widgets “out of the box” but there are some workarounds for this that you might be able to use:

Annotations.setCustomCreateInnerElementHandler(Annotations.TextWidgetAnnotation, function(annotationManager, { annotation, originalCreateInnerElement }) {
    const field = this;
    const el = originalCreateInnerElement();
    const label = document.createElement('label');
    const text = document.createTextNode(annotation.fieldName);

    // Wrapper div
    const wrapper = document.createElement('div');

    return wrapper;

(Note: using this would mean the styling used for TextWidgetAnnotations may not work correctly so you might also need to add custom CSS to make the text fields appear how you want them.)

As an alternative, you could also set tooltipName for your form fields to add a description when hovering the fields.
