Horizontal line
Horizontal Line - a component for displaying block separators. In the form builder, it is located in the View block.
An option Add vertical padding is provided for adding vertical padding.
Since forms are mainly displayed in modal windows, and modal windows have padding, it was decided to add an option Use negative margins (enabled by default), which allows increasing the width of the separator to the boundaries of the modal window.
To display the separator component only in view mode, you need to set the following condition Advanced display conditions in the Conditions tab:
show = instance.options.readOnly && instance.options.viewAsHtml
