Formatting HTML in Checkbox Widget

I have an issue with checkboxes not taking in HTML that would otherwise be properly formatted in an HTML Text widget. I’ve tried some workarounds like incorporating a checkbox input into the HTML widget itself but am unable to access the checked value from it through functions. Is there any way to pass in formatted HTML to checkbox values?

Found a loose workaround that involves using a checkbox widget and html text widget inside a nested basic container! You can leave the display values for the checkbox empty and just reference it without the displayed text.

Checkbox (or Radio) labels in Slate can only be plain Strings. The Tooltip Text can contain arbitrary HTML though, so as a workaround one can provide rich description of options available this way.
Also, if the desired formatting for Checkbox or Radio options is applicable to entire labels (say, they should be displayed in bold, in color or with different font-size or text alignment), one can use custom Styles (either for the particular widget or entire Slate app) and apply CSS to elements of “radio-label” class.
