Change the style of the InputText / Dynamic Text Box component

Hi overthere,
I’m trying to create a text editor using dynamic text box component
In fact, all works fine, changing the whole text as bold, italics, fonts, etc.
But i can’t change some substrings into the whole text, for italics, bold or something like this…

I don’t find any sample or documentation to get a partial string with some masks.

Any ideas?

Do you want to extract a piece text from text box and make it Bold or italics
