Hi Waghmare,

To work with offline tinymce requires below files.

tinymce.min.js, skin.min.css, content.min.css, tinymce.ttf and tinymce.woff

The folder structure should be like below.

skins (Folder) -> lightgray (Folder) -> content.min.css (Style Sheet)

skins (Folder) -> lightgray (Folder) -> skin.min.css (Style Sheet)

skins (Folder) -> lightgray (Folder) -> fonts (Folder) -> tinymce.ttf (File)

skins (Folder) -> lightgray (Folder) -> fonts (Folder) -> tinymce.woff (File)

You can get the required file from the below link.
