Content creation

Ahoj, pracuj na desktopové verzi interaktivní knihy. Potřebuji do knihy vložit externí html soubor, který by se měl zobrazit přímo na stránce knihy. Kniha i externí soubor budou na počítači bez přístupu k internetu ve stejné složce. Lze nastavit? Jak? Stále mám problém...

I am building an H5P game map but there are only a few stages that I need locked down until students complete the open stages. The problem is, when I open the activity, only one stage opens at a time. I want all of the stages open except for the few that have restrictions. What am I doing wrong?

In the Course Presentation there are only 2 heading levels available for the text formatting - Heading 2 and Heading 3.

I have two courses on the workdpress website with different branding. Therefore need to have additional heading styles.

I am using h5p mods plugin, and have added styles there, but that's obviously not enough.

Would should I do to add these headings to the formatting options? 

Thank you
