I want TinyMCE

Then you might need to adjust some CSS to make TinyMCE responsive on mobile.

Try to adjust the "skin.min.css" file in "oc-includes/osclass/assets/js/tinymce/skins/ui/oxide/"

Another thing I noticed. All menu icons will not be required in some cases. Once you reduced menu icons, I think that "width" related matter would be gone.

if i know coding, then why i 'm bought your product

@coco
Because you want to learn something new and want to be able to do some basic stuff on your site?

Go to responsive.css and add following code:
  body .tox .tox-toolbar--scrolling, body .tox .tox-toolbar--scrolling .tox-toolbar__group {white-space:normal;flex-wrap:wrap;}

after line @media screen and (max-width: 767px) {

thank you so much
